摘要： PROBLEM TO BE SOLVED: To provide a scroll compressor comprising a coating layer having uniform thickness, lubricity, and less friction, and producing small abrasion pieces even if it is worn.
SOLUTION: A coating layer 9 having an electroless nickel plated layer and a PTFE composite electroless nickel plated layer is formed on the surface of a movable scroll 5. The movable scroll 5 is fixed to a housing 12 by engaging with a fixed scroll 1. When this scroll compressor is operated, the portion of the PTFE composite electroless nickel plated layer on the surface of the movable scroll 5 in slidable contact with and rubbing on the fixed scroll 1 is worn, and a clearance between the fixed scroll 1 and the movable scroll 5 is almost eliminated. The coating layer 9 has a uniform thickness despite its complicated shape, and also has lubricity. Accordingly, the sliding loss of the movable scroll 5 is small. Since the abrasive pieces of the PTFE composite electroless nickel plated layer are fine, they do not clog in the scroll compressor.
