ABSTRACT:
A high temperature sliding alloy has a matrix1of a Ni-base alloy or a heat resistant Fe-base alloy, and contains, by mass, 1 to 35% hard particles consisting of a Co-base intermetallic compound dispersed therein, wherein 0.1 to 10% Ag is dispersed in the matrix. Ag is a soft metal, forms an ultrathin film on a sliding surface caused by sliding with a mating member, and presents a lubricating effect. When Ag forms the ultrafine film and spreads on the sliding surface, it works little as a frictional force against the mating member due to its low shear resistance, and accordingly can achieve a low coefficient of friction.
