Abstract

A highly reliable sliding face modification material capable of forming a stable film of molybdenum disulfide on the sliding face of a sliding member, the sliding face modification material having a molybdenum disulfide content of 95 wt% or more and an organic material content of 1500 ppm or less in weight ratio, and the sliding face modification material being projected onto the sliding face to form a coating layer.

Description

technical field [0001] The present invention relates to a sliding surface modifying material for modifying the sliding surface of a sliding member, a method for producing the sliding surface modifying material, a method for using the sliding surface modifying material, a sliding member having the sliding surface modifying material, and the use of the sliding surface modifying material. Compressor with sliding components. Background technique [0002] In recent years, from the viewpoint of global environmental protection, the development of energy-saving electrical equipment has progressed. For example, in compressors used in household refrigerators, etc., an energy-saving device that reduces the friction coefficient of the sliding surface of the sliding member is provided. equipment. [0003] In the prior art, a method of projecting molybdenum disulfide on the sliding surface of a sliding member, modifying the sliding surface, and forming a surface layer with a low coeffici...
