Abstract

The formation of a microstructure in the surface layers of model samples made of a titanium nickelide–based alloy intended for medical application during plasma immersion processing by silicon ions is studied. Depending on technological conditions, either a silicon coating can be formed or a surface layer can be alloyed. The formed layers have a high microhardness and high adhesion to the base material.

Keywords
