【 摘 要 】

Titanium and its alloys are commonly used in space, aviation, and motorisation industries due to their high strength and corrosion resistance. However, given its poor tribological properties (high friction and wear coefficients), methods for improvement of the tribological properties of titanium are continuously being developed. This study presents the effect of nitrogen ion implantation with energy 60 keV at a fluence of 1⋅1017 N+/cm2 on changes in the properties of titanium alloy Ti Grade 5 (Ti-6Al-4V). Ion implantation was carried out through a mask with φ = 500 μm diameter holes. Nitrogen implantation through the mask improve the tribological properties of Ti6Al4V, by reducing the mean value of the friction coefficient and reducing tribological wear.
