Low frictional ceramic material for sliding member

摘要

A low frictional ceramic material for sliding member, consists essentially of oxide of aluminum (Al) and oxide of zirconium (Zr) and contains oxide of cerium (Ce). Aluminum (Al) content is 50 to 75 wt.% in terms of alumina (Al2O3), zirconium (Zr) content is 20 to 45 wt.% in terms of zirconia (ZrO2), and cerium (Ce) content is 3 to 20 wt.% in terms of ceria (CeO2) in said low frictional ceramic material for sliding member. Instead of oxide of aluminum (Al) and oxide of zirconium (Zr), it is capable to use alpha -sialon. IMAGE
