Abstract

The invention provides a coating material, which comprises a base material and a membrane plated on the base material. The membrane comprises a bottom layer, a middle layer and a first surface course, which are sequentially arranged. The bottom layer directly contacts the base material and contains stainless steel; the middle layer comprises stainless steel and chromium; and the first surface course contains stainless carbide and / or nitride and chromic carbide and / or nitride. The invention also provides a preparation method of the coating material. The hardness of the membrane of the coating material provided by the invention is high and the bonding force between the membrane and the base material is good.

Description

technical field [0001] The invention relates to a coating material and a preparation method thereof. Background technique [0002] At present, coating materials are increasingly widely used in industrial sectors such as aviation, aerospace, chemical industry, shipbuilding, and communications. Generally, coating materials include substrates and films coated on the surface of substrates. Common films are transition metal carbides or Nitride thin films, the carbides or nitrides of these transition metals have stable chemical properties, good chemical corrosion resistance, high melting point and hardness, and can be used to prepare hard films by magnetron sputtering. Deposition, but the prepared hard film has the defect of poor bonding with the substrate. [0003] For example, CN 1740394A discloses a hard wear-resistant protective film product, including a substrate and a film vapor-deposited on the surface of the substrate, characterized in that the film is a Ti-based film or ...
