摘要

Due to the environmental concerns, especially the greenhouse effect and GWP (Global Warming Potential), the carbon dioxide was investigated as an alternative natural refrigerant to replace HFCs (HydroFluoroCarbons) in refrigerator or air conditioning systems. To develop new compressor, especially rotary type, the friction and wear characteristics of sliding surfaces between vane and flange in the rotary compressor were evaluated in this paper. Several hard coatings, such as TiN, CrN and WC/C, were applied on vane surfaces in order to improve the tribological characteristics, and their performances were evaluated experimentally. The vane-on-flange type lubricated sliding tests were performed with a high pressure wear tester using HFC (R410A) and carbon dioxide. From the tests, wear volumes of vane surfaces applied with various coatings were compared each other.
