【 摘 要 】

The article reports findings on the study of microhardness and wear resistance of Ti-Cu coatings produced by a complex technology. It is established that within the temperature range under investigation (20 to 400 °C) the wear resistance of non-alloyed coatings exceeds copper wear resistance three-fold, while the wear resistance of alloyed coatings exceeds copper wear resistance eight-fold; the fact is attributed to a higher hardness of alloyed coatings.
