Various types of metal implants, both in Poland and worldwide, are mainly manufactured from stainless steel due to their biocompatibility, strength, and relatively low price. However, any such procedure involves the risk of peri-implant infection, stimulated, among other things, by the formation of a bacterial biofilm on the surface of the implant. In this paper, several methods of modifying the surface of steel for medical applications were proposed, such as mechanical polishing, electropolishing, sandblasting, and the application of a thin surface layer. This was followed by a series of physicochemical and biological tests. The results indicate that the titanium nitride coating improved corrosion resistance and reduced bacterial adhesion on the surface. No significant improvement in abrasion was observed, and the adhesion of the coating closely depended on the method of preparation.

Implanty metalowe, zarówno w Polsce, jak i na świecie, produkowane są głównie ze stali nierdzewnej ze względu na jej biokompatybilność, wytrzymałość i stosunkowo niską cenę. Jednak każdy tego rodzaju zabieg wiąże się z ryzykiem powstania zakażenia okołowszczepowego, stymulowanego m.in. powstawaniem biofilmu bakteryjnego na powierzchni implantu. W pracy zaproponowano kilka metod modyfikacji powierzchni stali do zastosowań medycznych, takich jak polerowanie mechaniczne, elektropolerowanie, piaskowanie oraz nałożenie cienkiej warstwy powierzchniowej. Następnie przeprowadzono szereg badań fizykochemicznych i biologicznych. Wyniki wskazują, że powłoka azotku tytanu poprawiła odporność na korozję oraz ograniczyła adhezję bakterii na powierzchni. Nie zaobserwowano znaczącej poprawy ścieralności, a adhezja powłoki ściśle zależała od metody jej przygotowania.

Scientists and medics are still searching for new metallic materials that can be used in medicine, e.g., as material for implants. The following article proposes materials based on titanium with vital elements prepared by combined powder metallurgy and arc melting methods. Four compositions of Ti-28Ta-9Nb, Ti-28Ta-19Nb, Ti-28Ta-9Zr and Ti-28Ta-19Zr (wt.%) have been prepared. The tested material was thoroughly analyzed by X-ray diffraction and scanning electron microscopy. Qualitative phase analysis using X-ray diffraction showed the presence of two phases, α' and β titanium. In addition, a microhardness test was conducted, and the material was characterized in terms of corrosion properties. It was found that the corrosion resistance decreases with an increase of the β phase presence.

This work investigated two titanium-based alloys with a constant tantalum content and variable contents of alloy additives - niobium and zirconium. The Ti-30Ta-10Zr-20Nb (wt.%) and Ti-30Ta-20Zr-10Nb (wt.%) alloys were obtained using a combination of powder metallurgy and arc melting methods. The influence of alloying additives on the structure and properties of the Ti-Ta-Nb-Zr system was studied using, among others: X-ray diffraction and scanning electron microscopy. The X-ray diffraction confirmed the single-β-phase structure of both alloys. In addition, the microscopic analysis revealed that a higher amount of zirconium favoured the formation of larger grains. However, the microhardness analysis indicated that the alloy with the higher niobium content had the higher microhardness. Importantly, the in vitro corrosion study revealed that the addition of niobium promoted the better corrosion resistance of the investigated alloy.

A promising strategy for fighting the bacterial biofilm on the surface of biomaterials involves modification of their surface with the use of bactericidal and bacteriostatic coatings. Ongoing studies concentrate on the development of material that can limit bacterial colonisation and is safe for the human organism. Therefore, the current research focuses on the conditions related to implant coating to limit biofilm formation. However, previous outcomes in this area have not been satisfactory. Accordingly, the main goal of the carried out tests was to study the impact of the physicochemical properties of the surface layers on the course of processes taking place on the surface of implants made of metallic biomaterials used in the bone system. The surface of the analysed biomaterial -316LVM steel - was modified using such processes as grinding, electrochemical polishing, sandblasting, application of a ZnO layer using low-temperature Atomic Layer Deposition (ALD), and medical sterilisation. Initial assessments involved the chemical composition, phase composition, and the microstructure of the surface layer. The last stage involved microbiological studies, including an assessment of the adhesion of Gram-positive and Gram-negative bacteria to the modified surface, proliferation of MG-63 osteoblast-like cells and cytotoxicity tests. The analysis of adhesion of S. aureus and E. coli colonies confirmed that the ZnO coating is effective in reducing bacterial adhesion to the 316LVM steel substrate, regardless of the number of cycles, process temperature and surface treatment method.
