The peculiarities of structure surface layer forming of Ti-alloy by laser alloying by B, C and Cr are presented in this work. The surface layer by the laser alloying consists of great quantity of small particles of borides, carbides and intermetallides which raise the hardness of the surface to 9500 - 11500 MPa. The antifriction properties investigation shows that the wear of Ti-alloy surface is reduced after the laser alloying. The addition of solid oiling into the alloying composition allows us to reduce the coefficient of friction to the sizes that correspond to the coefficient of friction of the traditional anti-friction materials. |
