Abstract
A compressor, characterized in that a steel is used as the base material for the other sliding material vaneand nitrided, a CrN or DLC film is formed on the surface by PVD treatment, and a Ni—Cr—Mo cast iron is used for the other corresponding sliding material piston. It is possible in such a configuration to suppress the temperature rise by sliding friction of the sliding materials, such as the vane tip regionand the peripheral region of pistonthat are vigorously slid, relax decomposition of the refrigerant, and suppress corrosion by hydrogen fluoride generated in reaction with water and oxygen, and thus to provide a compressor higher in reliability.
