Title:
HIGH-TEMPERATURE SUPER-LUBRICATION SILICON-DOPED DIAMOND-LIKE CARBON FILM, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/099027
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of surface treatments, and disclosed are a high-temperature super-lubrication silicon-doped diamond-like carbon film, and a preparation method therefor and the use thereof. The high-temperature super-lubrication silicon-doped diamond-like carbon film comprises a Cr priming layer, a CrxSiyCz gradient transition layer and an Si-DLC functional layer which are sequentially arranged on the surface of a substrate. Further disclosed is a method for improving the friction and wear performance of a matrix. The high-temperature super-lubrication silicon-doped diamond-like carbon film is prepared on the surface of the matrix, such that during friction in a high-temperature atmospheric environment, a compact transfer film composed of amorphous carbon and SiOx is formed in situ at a friction pair.
