SLIDING DEVICE, ITS MANUFACTURING METHOD AND REFRIGERANT COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a sliding member reducing a friction coefficient of a sliding part and improving galling resistance, seizure resistance and wear resistance, a manufacturing method of the sliding member and a refrigerant compressor.

SOLUTION: In this sliding device, each sliding surface composed of a ferrous member has a hard carbon film. Hardness (HV) of the member is 250 or more, and surface roughness of the member (Ra)is below 0.3 μm.
