Preparation of metal doped diamond-like surface ion liquid lubricant self-assembled lubricating film

Abstract

The invention discloses a method for preparing a metallic contamination adamantine surface ionic liquid lubricant self-assembly lubricative film. The method takes ionic liquid lubricant as raw material, adopts magnetron sputtering equipment to prepare a metallic contamination adamantine carbon film and assembles the liquid lubricant film which is stable, uniform and ordered on the carbon film. The method is characterized in that the preparation process is operated at normal temperature, and the requirements for the material and the shape of a substrate are lower; the film is stable and uniform, and has lower surface roughness; the film also has good performances on antifriction, wear resistance and adhesion resistance. The test of friction and wear proves that the ionic liquid lubricant and adamantine has good combining performance and better performances on antifriction, wear resistance and adhesion resistance, so that the lubricative film is expected to become the effective means of solving the problems of protecting and lubricating materials I the technical fields such as space machinery, information technology, etc.

Description

technical field [0001] The invention relates to a method for preparing a metal-doped diamond-like surface ionic liquid lubricant self-assembled lubricating film. Background technique [0002] Diamond-like carbon (DLC) film has high hardness, low friction coefficient, high wear resistance and good chemical stability, thermal conductivity, electrical insulation, light transmission and biocompatibility as a new functional film material in mechanical resistance It has broad application prospects in abrasive coatings, optical windows, microelectromechanical systems (MEMS) and semiconductor materials. However, studies have found that huge internal stress and poor bonding force are two major defects of diamond-like carbon film, which largely restrict its development. The internal stress of the diamond-like carbon film is as high as several GPa, which not only reduces the bonding strength between the film and the substrate, causes the failure of the film during use, but also limits...
