PROBLEM TO BE SOLVED: To provide a compressor improving seizure resistance of a sliding member and achieving high durability since there is risk that shortage of lubricating oil and rapid temperature rise accompanying the same occur during transient operation and heavy load operation and seizure occurs at a sliding member in a high capacity system since silicon of a surface layer part is covered by aluminum and the uppermost surface is rich in aluminum due to working. SOLUTION: In this compressor, the sliding member of aluminum-silicon alloy on which boiling water dipping treatment applied is used for a turning scroll of a scroll compressor and the like. Coating of hydrated oxide of aluminum is formed on a surface of the sliding member, seizure resistance is greatly improved and high durability is achieved. COPYRIGHT: (C)2011,JPO&INPIT
