Purpose: of this paper was comparison of the structure, hardness and erosive wear of aluminium coatings produced on non-alloy structural steel S355JR (EN 10025-2) using the powder flame spraying and wire arc spraying methods. Design/methodology/approach: The latest model of flame powder sprayer and wire arc sprayer was used in the experiments. This provided very reliable spraying conditions. The additional material for flame-spraying was of Metco 54NS-1 pure aluminium powder (EN AW 1100 series). In the arc spraying process the Metco Aluminium (EN AW 1100 series) 1.6 mm diameter pure aluminium thermal spray wire was used. In each spraying technology binding alloy, i.e. Ni-Al, was employed as a primer coating. The used spray processes produced dense, abrasion and erosion resistant coatings approximal 1.0 mm thick. Aluminium coatings were characterized in accordance with ASTM G 76-95 erosion resistance tests, ASTM C 633-01 adhesion strength, HV 0.1 hardness tests and metallographic analyses. The scope of research included: preparation material for spraying, selection of properly process parameters for each sprayed technique based on preliminary technological tests, coatings manufacturing, examining the structure and tribological properties of aluminium coatings, comparison of obtained samples. Findings: The obtained results have proven superior properties of arc sprayed aluminium material coatings and have shown to be promising in industrial applications. Research limitations/implications: The presented test results are a preliminary assessment of the properties of thermally sprayed aluminium coatings. Therefore, further research is required regarding the resistance of aluminium coatings to abrasion and corrosion. Practical implications: The study is focused on selecting the best and most economical technique for manufacturing of wear and corrosion resistance aluminium coatings with a thickness of approximately 1 mm. Originality/value: It has been demonstrated that the use of a Ni-Al primer coating improves the adhesion of flame and arc sprayed aluminium coatings to steel surfaces.

W artykule przedstawiono wyniki badań właściwości powłoki z nanostopu na osnowie żelaza z dużą ilością drobnych wydzieleń w postaci węglików, natryskiwanej łukowo na płyty ze stali niestopowej ASTM A516, Grade 55 przeznaczonej do pracy w podwyższonej temperaturze. Do natryskiwania łukowego wykorzystano najnowszej generacji urządzenie spawalnicze Eutronic Arc Spray 4, zapewniające dużą stabilność procesu. W badaniach posłużono się metalicznym drutem proszkowym EnDOtec DO*390N o średnicy 1,6 mm. Wykonano powłokę grubości 1,0 mm, odznaczającą się dużą odpornością na zużycie ścierne i erozyjne.

Study of the laser powder cladding of titanium alloy Ti6A14V plates by nickel based powder are presented. The high power diode HPDL, with a rectangular beam spot and a uniform, multi-mode energy distribution across the spot, was used for cladding trials. Influence of the basic parameters of laser cladding on the shape and quality of surface layers was determined. High quality and cracks free surface layers with smooth face and regular shape were produced on titanium alloy substrate by laser cladding with HPDL laser and nickel based powder. To ensure high quality of the surface layers during laser cladding of titanium alloy, gas shielding of the weld pool and also the solidified clad must be applied by high purity argon. Moreover the range of optimal laser cladding parameters is very narrow.

Comprehensive study of nano-material wire arc spraying technology were conducted to establish optimum properties of very high wear resistance coatings of nano-material sprayed on ASTM A516, Grade 55 base metal sheets. Newest model of wire arc spraying equipment - Eutronic Arc Spray 4, was used during experiments, providing very reliable spraying conditions. Messer-Castolin-Eutectic powder metal cored wire EnDOtec DO*390N 1,6 mm dia, was used to produce, dense, very high abrasion and erosion resistant coatings of thickness approx. 1.0 mm. Nano-material coatings characterization was done in accordance to ASTM G 65-00 Procedure A abrasion resistance test. ASTM G 76-95 erosion resistance tests, ASTM C 633-01 adhesion strength, HV 0,1 hardness tests and metallographic examinations. Results have proved high properties of arc sprayed nanomaterial coatings and have shown promising industrial applications.
