Cryogenic treatment of diamond-like vacuum coatings

The article considers the cryogenic treatment of diamond-like coatings formed on tool die steel. It studies the morphology, physical-mechanical, adhesive, and tribological characteristics of carbon coatings treated by hybrid technology, which consists of the complex effect of cryogenic liquid on both the metal substrate and the system “modified steel substrate-diamond-like coating”. It also studies structural transformations occurring in vacuum coatings formed on steel substrates with subsequent treatment at low temperatures. The change in the tribological characteristics of diamond-like coatings during hybrid treatment in cryogenic liquid is shown.
