| | ABSTRACT | | Titanium and its alloys, primarily Ti-6Al-4V and Ti-6Al-7Nb, are widely used in various high-tech sectors due to their excellent mechanical properties, high corrosion resistance, and low density. However, these materials exhibit low wear resistance and a tendency to gall during friction, limiting their applicability in aggressive environments or under heavy loads. This review discusses the main challenges associated with the tribological properties of titanium alloys and various modern surface modification techniques, including chemical and electrochemical methods, laser coatings, ion implantation, and nanocoatings. The advantages of these techniques in improving wear resistance are analyzed, with a focus on applications in aerospace and medicine. Special attention is given to the impact of friction in different environments and the anti-friction properties of titanium alloys. The review highlights the need for further development of surface modification technologies to enable broader use of titanium and its alloys in extreme conditions and to extend their service life. |
