Abstract:
1. A high temperature sliding alloy comprising (1) a Ni-base alloy, (2) by mass, 1 to 35% of hard particles consisting of a Co-base intermetallic compound, and (3) 0.1 to 10% Ag as a separate phase, wherein the hard particles and Ag are dispersed in a matrix of the Ni-base alloy, and wherein the Ni-base alloy consists essentially of, by mass, 2 to 8% Cr, 2 to 10% Fe, 0.1 to 1.5% Si, 1.4 to 11% Mo, the balance of the Ni-base alloy being Ni and incidental impurities, and said mass percentages of the above component elements being based on the whole sliding alloy.
