Abstract:
The present invention provides a method for manufacturing a vane to be used in a compressor comprising a cylinder, a piston orbiting along the inner circumference of the cylinder, and end plates sealing both ends of the cylinder, the vane being provided in a vane groove of the cylinder so that a cylinder chamber formed between the cylinder and the piston is divided into an intake chamber and a compression chamber, the method comprising: forming, from a base material with a Cr content exceeding 4.5 wt%, a vane (127) having a tip surface (129a) to slide against the outer circumference of the piston; forming a high hardness coating layer (211) on at least the tip surface (129a) of the vane (127); and nitriding the vane (127) after the formation of the high hardness coating layer (211).
