Abstract

PURPOSE:To contrive at enhancing the durability and wear-resistance of component parts such as vanes, a roller, a crankshaft or the like made of iron group materials by forming a coating layer in which at least one kinds of predetermined carbide and nitride is dispersed, on the outer surface of a slide part of each component. CONSTITUTION:A rotary compressor is composed of a motor section A and a compressing mechanism section B. Further, in the motor section A, a rotor 3 is rotated by a stator 1 so as to rotate a crankshaft 7. Meanwhile, a cylinder 2 is disposed in the compressing mechanism section B, and vanes 9 are slidably disposed in a vane slot section of the cylinder 2. Further, the crankshaft 7 is extended into the compressing mechanism section B, and a roller 8 is eccentrically rotated in the cylinder 2. In this arrangement, each of the vanes 9, the roller 8 and the crankshaft 7 has its outer surface made of iron group materials and formed thereon with a coating layer made of metal nitride and metal carbide.
