Experiments were conducted to determine the friction and wear characteristics of aluminum bronzes and copper--tin, titanium--tin, and copper--silver alloys sliding against a titanium--6% aluminum--4% vanadium alloy (Ti--6Al--4V). Hemispherically tipped riders of aluminum bronze and the titanium and copper alloys were run against Ti--6Al--4V disks in air at 430 C. The sliding velocity was 13 cm/s, and the load was 250 g. Results revealed that high-tin-content titanium and copper alloys underwent significantly less wear and galling than commonly used aluminum bronzes. Also friction force was less erratic than with the aluminum bronzes. (auth)
