This article presents the structure and properties of surface layers produced on 30HNWFAŻ steel in processes of glow discharge (g.d.) nitriding and its modified versions, vis: the IMPAS method, i.e. nitriding with successive oxidation under g.d. conditions, and the WIMP method consisting in connecting the g.d. nitriding with the PACVD technique under the g.d. conditions in an atmosphere containing an organic compound of titanium - Ti(OCH). Discussed are the results of metallographic examinations, hardness test, phase composition tests, resistance to wear due to friction and corrosion of the layers produced in the new processes. By way of example results are quoted of comparative examinations relative to a chromium layer deposited electrolytically. It has been proved that the layers produced under the g.d. conditions substantially improve the useful properties of the 30HNWFAŻ steel.

The aim of the present work is to determine the influence of technologically produced boron surface layers on the friction parameters in the sliding pairs under the conditions of mixed friction. The tribological evaluation included ion nitrided, pack borided, laser borided, quenched and tempered surface layers and TiB2 coating deposited on 38CrAlMo5-10, 46Cr2 and 30MnB4 steels. Modified surface layers of annular samples were matched under test conditions with counter-sample made from AlSn20 bearing alloy. Tested sliding pairs were lubricated 15 W/40 Lotos mineral engine oil. The tribological tests were conducted on a T-05 block on ring tester. The applied steel surface layer modification with boron allow creating surface layers with pre-determined tribological characteristics reąuired for the elements of kinematic pairs operating in the conditions of sliding friction. Pack boronizing reduces the friction coefficient during the start-up of the frictional pair and the maximum start-up resistance level is similar to the levels of pairs with nitrided surface layers. Paper present comparison between surface roughness of annular sample and countersample before and after test, influence of surface treatment annular sample on change of friction coefficient vs. rotation speed and load, influence of surface treatment annular sample on moment of friction in function load of kinematics pair, influence of surface treatment annular sample on friction forces and temperature depending on load, as well as influence of surface treatment annular sample on wear of AlSn20 bearing alloy under various load conditions.

Purpose: The main aim of this work is to present our investigation in the field of photoalignment. In this work we introduce useful photoalignment techniques and discuss in detail the results of photocrosslinking and photodegradation in photosensitive polymer materials. Design/methodology/approach: We describe the new procedure investigated in our laboratory for the following materials: HD-4100, HD-4110 and HD-8820 (DuPont Microsystems) as well as the characteristics obtained for the thin polyimide layers: optical homogeneity, thickness, surface tension. Findings: Polyimide layers obtained on the glass/ITO substrates which were irradiated using linearly polarised ultraviolet light show the aligning properties for liquid crystal layers. The proposed new technology is fairly fine to obtain 2-3 cm2 layers. Research limitations/implications: The liquid crystal material alignment quality is not perfect, but the works are still in progress. In the next step we will try to use silan-derivative adhesion promoters to lower the aligning layers thickness. This solution will probably also have a big influence on the aligning layers homogeneity. Practical implications: We discuss an alternative technique of the rubbing method for composition of liquid crystal displays. Liquid crystal displays are widely used for many industrial and commercial applications. Multimedia and graphics and medical-imaging systems require top quality images. Such an image can be obtained under the condition of good liquid crystal alignment. Rubbing is a method conventionally used for these purposes. Unfortunately this technique has some disadvantages that are particularly visible in new generation displays. The usage of photodephiniable materials opens the route to obtain an appropriate molecular tilt and controlled anchoring energy as well as preparing layers that are suitable to providing diversified optical axes in one liquid crystal cell. Originality/value: Agents investigated in the paper hasn’t been used as the alignment materials in liquid crystal cells preparation so far. The used technology as well as HD-4100, HD-8820 and HD-4110 materials are suitable as the alternative substances for common used aligning chemical substances and technologies.

Laser cladding is a method that can be applied to repair the crack and break on the mold and die surfaces, as well as generate new attributes on the surface to improve toughness, hardness, and corrosion resistance. It is used to extend the life of the mold. It also has the advantages of superior bonding strength and precision coating on a local area compared with the conventional thermal spraying technology. In this study, we investigated the effect of cladding on low carbon alloy steel using 18%Cr-2.5%Ni-Fe powder (Rockit404), which showed high hardness on the die surface. The process conditions were performed in an argon atmosphere using a diode laser source specialized for 900-1070 nm, and the output conditions were 5, 6, and 10 kW, respectively. After the cladding was completed, the surface coating layer’s shape, the hardness according to the cross-section’s thickness, and the microstructure were analyzed.

Purpose: In the paper physical (surface topography, electrical properties) and antithrombogenic properties of the passive-carbon layer used for enhancing the surface properties of vascular stents made of Cr-Ni-Mo steel have been investigated. Design/methodology/approach: To characterize the electrical properties of carbon layer the silicon plate was used. The resistivity ρ and relative permittivity of the layer ε r have been determined on the basis of currentvoltage and capacitance-voltage characteristics. In vitro tests of biotolerance evaluation of the passive-carbon layer in blood environment have been carried out in the haemolysis tests (in the direct contact and from the extract) and in the blood clotting tests. Findings: The results of investigations have shown that deposition process of the passive-carbon layer of dielectric properties on the surface of implants made of Cr-Ni-Mo steel and used in interventional cardiology is an effective way of limiting the reactivity of their surface in blood environment and the blood clotting process in consequence. Research limitations/implications: Usefulness of the passive-carbon layer for interventional cardiology applications should be verified in in vivo tests. Originality/value: Modification of physical properties of surface of the metallic biomaterials applied in cardiovascular system by deposition of the passive-carbon layer which has dielectric properties limits the blood clotting process.

Purpose: The aim of the work was to work out methods to improve biocompatibility of the Ti6Al7Nb alloy by creating thick, porous layer which ensure corrosion resistance and which could be a base for biological reactions leading to improvements in the tissue bond with the implant. Design/methodology/approach: Surface were prepared using electropolishing, thermal oxidation, thermal oxidation in TiO2 powder, anodic oxidation in NaH2PO4, in NaOH and spark oxidation in H2SO4+H3PO4. The roughness was examined using MSP and LPM. Corrosion resistance tests were carried out in SBF with pH values characterized for neutral, inflammatory and stagnation state. Topographical features were determined using confocal microscope. Findings: The surface treatments guarantee a smooth surface (low value of Ra and RZDIN) or porous surface structure and high corrosion resistance. Topographical parameters of the layer can be altered according to the duration of that process. The corrosion resistance of the specimens anodically oxidized in NaOH and spark oxidized possessed high corrosion resistance in SBF also in SBF with low and high pH value. Research limitations/implications: For the layers, further mechanical, chemical, biological and composition examinations are planed. Practical implications: The paper presents different surface treatments and their influence on corrosion and topographical properties and it could be useful for implant producers to take into consideration one of these methods. Anodic oxidation is a very simple method to ensure high corrosion resistance of implants. Originality/value: The paper presented new approaches to the surface preparation by spark oxidation in the acids and anodic oxidation in NaH2PO4 and NaOH at different parameters which haven't previously been used. There were proposed thermal oxidation in TiO2 powder that was not presented before. The paper compares corrosion resistance and topographical features of the Ti6Al7Nb modified by the new proposed and commonly used techniques.

Purpose: The purpose of the work was to create homogenous surface layer as a result of impulse laser alloying of TiO2 and low-alloy steel. Design/methodology/approach: The surfaces of samples, coated with ceramic coating, were then irradiated with CO2 laser beam. During the work microstructure and phase investigations as well as measurement of microhardness have been carried out while the chemical composition of the surface layers has been determined. Findings: The microstructure in all the paths created as a result of application of varied processing parameters was comparable. Chemical composition of individual zones which were a result of remelting proved creation of a surface layer rich in Ti. Research limitations/implications: Further research is aimed to determine corrosion resistance of the alloyed samples. Practical implications: TiO2 layers are widely applied e.g. in medicine which makes them an object of unflagging interest by researchers. Originality/value: Microstructure description of the alloyed surface layer cohesive-connected with base material, which eliminated fundamental problem involved with the created layers i.e. their poor adhesion, has been presented.

The effects of HCl-based chemical and Ar+ sputter etching treatment on (100) GaAs surface properties with the aim to develop the procedure of surface preparation before metal deposition have been investigated. Variable angle spectroscopic ellipsometry, X-ray photoelectron spectroscopy, atomic force microscopy and photoluminescence have been used to study the surface characterization. We show that combining chemical etching in 5% HCl with Ar+ sputter etching gives the best results for surface cleaning prior to metal deposition. The application of this two-step treatment allows to obtain Ni/AuGe/Ni/Au ohmic contact with rc = 2×10–6 .omega.cm2 with excellent adhesion and long-term thermal stability.

Image analysis is an innovative solution in material characterization. One of the areas where image analysis can be put to use effectively is in establishing the thicknesses of coatings encountered in surface fi nishing applications. Galvanizing ranks among the most widely used corrosion protection techniques, and estimates of the useful service life of surface-finished substrate material hinge on establishing the correct thickness of the zinc layer applied in the galvanizing process. In applications where the fi lm thickness does not lend itself easily to measurements by common thickness gauges (such as on highly curved surfaces), a method which, in addition to fi lm removal by etching, is well-suited for measuring thicknesses is using the microscope. Prior to the measurement, polished metallographic sections are prepared from suitable specimens, and the measurement itself is conducted as per the standard EN ISO 1463 [1]. The thickness measurement proper is performed at regular intervals around the sample periphery, where the sample is allowed to travel within the optical system of the microscope and the readings are compared with a calibrated scale of the eyepiece. In case image analysis technique is used, the over-all, as-recorded image of the sample provides the input data for a software separation process by which the image of the Zn layer is isolated and, subsequently, evaluated using image analysis software. From comparisons of the results achieved it follows that the use of image analysis, which is also less time-consuming, yields more accurate results.

Metoda analizy obrazu to nowoczesne rozwiązanie stosowane w charakterystyce materiałów. Metoda ta znajduje praktyczne zastosowanie m.in. w ustalaniu grubości powłok w procesie obróbki powierzchniowej. Cynkowanie jest metodą najszerzej stosowaną w ochronie przed korozją i założona trwałość pokrytego powłoką podłoża po obróbce powierzchniowej wpływa na ustalenie odpowiedniej grubości powłoki cynku nałożonego w procesie cynkowania. W przypadkach gdy grubości nie można w łatwy sposób zmierzyć za pomocą standardowych urządzeń pomiarowych (np. gdy powierzchnie są mocno zakrzywione), oprócz techniki polegającej na usunięciu powłoki przez wytrawienie zastosowanie znajduje również metoda mikroskopowa. Przed wykonaniem pomiaru przygotowane zostają wypolerowane próbki metalografi czne, a sam pomiar jest wykonywany według normy EN ISO 1463 [1]. Grubość właściwa mierzona jest w równych odstępach w obrębie próbki, gdy próbka przesuwana jest w polu widzenia systemu optycznego mikroskopu, zaś odczyty porównywane są ze skalibrowaną skalą na okularze. W przypadku zastosowania metody obróbki obrazu, dane wejściowe uzyskane bezpośrednio z zarejestrowanego obrazu zostają przesłane do odpowiedniego programu, który następnie izoluje warstwę cynku aby później poddać ją obróbce. Na podstawie porównania wyników ustalono, że zastosowanie metody obróbki obrazu pozwala na uzyskanie bardziej dokładnych wyników w krótszym czasie.

The paper investigates the effects of degreasing, surface preparation methods in adhesive bonding and con adhesive joint strength. Five types of degreasing agents were used in the study: acetone, extraction naphtha, Ultramyt, Wiko and Loctite 7061. The degreasing operation was performed by three methods: rubbing, spraying and immersion. Strength tests were performed on single-lap adhesive joints of hot-dip galvanized metal sheets made with Loctite 9466 adhesive according to the above variants of surface preparation. The experimental results demonstrate that adhesive joint strength is significantly affected by the applied degreasing agent. Moreover, the method of application of the degreasing agent is crucial, too. The results of strength testing reveal that the most effective degreasing method for hot-dip galvanized metal sheet adhesive joints is spraying using extraction naphtha. Thereby, degreased samples have the highest immediate strength and shear strength. The use of extraction naphtha is also effective in combination with degreasing by rubbing; however, it is not effective when used in combination with immersion, as reflected in the lowest strength results.

Investigations include alloying the PMHSS6-5-3 steel surface layer with carbide and ceramic powders WC, VC, TiC, SiC, Si3N4 and Al2O3, using the high power diode laser (HPDL). Laser treatment is especially promising for solving contemporary surface engineering problems making it possible to focus precisely the delivered energy in the form of heat in the surface layer. The structural mechanism was determined of surface layers development, effect was studied of alloying parameters, method on structure refinement and influence of these factors on the mechanical properties of surface layer, and especially on its abrasive wear resistance. The fine grained martensite structure is responsible for hardness increase of the alloyed layer. The tribological wear relationships were determined for laser treated surface layers, determining friction coefficient, and wear trace shape developed due to the abrasive wear of the investigated surfaces. Comparison of the laser treatment parameters and tribological properties of surface layer after remelting and alloying with hard particles of the PMHSS6-5-3 steel using the high power diode laser to obtain the optimum service properties is the outcome of the investigations carried out.
