摘要: Abstract The sliding behaviors of two typical high-temperature alloys GH2132 and GH605 against WC SiC balls were investigated at environments from room temperature to 800 °C with a speed 50 125 m/min under load 10 20 N. wear performances alloys, rated their mechanisms discussed. four pairs exhibited the markedly different behaviours, in which GH2132/WC pair had maximum friction coefficient 10 N temperature. variation trends ball rates ambient odds those coefficient. higher did not always lead suffer rate. worn depth approximated 250 μm for GH605/WC lower plate. Whether or high temperature, GH605/SiC significantly good resistance minor damage plate despite its
