Abstract
At present, the research on deep cooling times mainly focuses on the influence of a certain material. The research on the deep cooling treatment process of the coating composite system focuses on the insulation time, deep cooling temperature, and cooling rate, and there are few studies on the influence of deep cooling times on the coating composite system. This paper preliminarily explored the influence of the cryogenic treatment process changing cryogenic times on the structure and properties of the diamond-like carbon film (DLC) coating on an M35 high-speed steel surface under the condition of a certain total holding time. When two cryogenic treatments were carried out at -140°C and -196°C, the content of the SP3 hybrid bond decreased. The bonding force of DLC coating is improved after several cryogenic treatments, but the wear resistance of DLC coating decreases with the further increase of cryogenic times. This process has certain reference significance for improving the bonding force and wear resistance of DLC coating.
