Hochtemperatur-Gleitlegierung und diese verwendende Gleitkontaktstruktur

摘要

There is disclosed a high temperature sliding alloy consisting of, by weight, 2 to 8% Cr, 2 to 10% Fe, 0.1 to 1.5% Si, 2 to 22% Co, 1.4 to 11% Mo, and the balance Ni, wherein 1 to 35% by weight of Co-Mo-Cr-Si base hard particles are dispersed in a matrix of the sliding alloy, and each of the hard particles has an oxide phase formed on a surface thereof. With this construction, the sliding alloy exhibits excellent sliding properties and particularly a low friction coefficient and excellent wear resistance in the temperature range of from a room temperature to 900° C.
