Abstract
In connection with the limitation of flon gas usage in order to protect earth environment, the wear and galling of vanes and rollers for rotary type refrigerators and air-conditioners have been concerned. We have investigated vane materials, roller materials and their combinations which can stably be used in new refrigerants and lubricants. The evaluation method for wear resistance and galling resistance were established and those of tool steels and cast irons with different chemical compositions, structural factors, hardness and surface treatment conditions were investigated quantitatively. It was found for vane materials, that the addition of TiN particles, the increase of MC carbides, the increase of hardness and nitriding treatment were effective for preventing galling. Particularly, the materials having TiN particles and nitrided ones showed superior galling resistance to carbon vanes. It was also found for roller materials, that the galling resistance increased as P content in the material increased.
