Problems solved by technology

Among them, arc ion plating has high ionization rate and energy, and is usually used to deposit hard films, but the deposited films have large roughness, which is not suitable for the processing of precision components; although traditional magnetron sputtering can obtain films with excellent properties, However, there are problems of poor plating and bonding force, and the film thickness difference is large in the vertical direction away from the target; chemical vapor deposition technology usually requires high temperature to achieve good bonding force, although plasma-enhanced chemical vapor deposition can Low-temperature deposition is achieved, but it is difficult to achieve large-area deposition due to high deposition conditions; although the magnetic filter arc solves the problem of film surface finish, the high deposition temperature and long deposition time make it difficult to industrialize

[0006] In order to solve the problem that the industrialization of consistent fullerene-like films cannot be obtained on the surface of the engine friction pair due to poor film-base bonding and uneven film thickness, the present invention provides a multi-layer composite film with high bonding force and uniform film thickness. A method for preparing fullerene films, which can realize the industrialization of fullerene-like films on various friction pair parts and materials in engines
