摘要：

This work presents data on the properties of the surface layer of OT-4-0 titanium alloy after nitrogen implantation. Polished samples were implanted with nitrogen doses of 1x10(17) and 6x10(17)cm(-2). The corrosion resistance was examined by the potentiodynamic method in 0.5 M NaCl and 15% H2SO4 solutions. Transmission electron microscopy was used to investigate the microstructure of the implanted layers formed on OT-4-0. It was found that the implanted layers consist of a dispersion of fine TiN particles in a deformed matrix of alpha-Ti. Nitrogen implantation increases the corrosion resistance and microhardness.
