摘要：

Wear tests have been conducted on a reciprocating high temperature rig at 750 degrees C and a load of 7N using a Stellite 6 and Incoloy 800 counterface. The ODS alloys (MA956, PM2000 and PM2000SD) all showed poor wear resistance and the absence of glaze formation when worn against Incoloy 800. Glaze formation occurred when the ODS alloys were tested against Stellite 6 providing very good wear protection. Nimonic 80A tested under similar conditions exhibited good wear resistance against Incoloy 800 (presence of glazes) and poor wear resistance against Stellite 6 (absence of glazes). Titanium aluminide showed very good wear resistance when tested against Incoloy 800 and Stellite 6. In both cases, the glaze and underlying oxide particles were entirely formed from the counterface material. These results show the strong influence of the counterface materials on the formation of wear resistant glazes.
