ABSTRACT	Pin-on-disk tests were carried out at temperatures up to 450°C in a vacuum using a self-lubricating composite pin.The composites uswear resistance was also obtained with an M-50 tool steel disk.In both cases,a thin transfer film was formed on the disk surface from the composite pin.A considerable amount of wear,for both the composite pin and steel disks,was observed when the disks had a low hardeess,such as SUS304 disk,and not-hardened SK-3 and SKD-11 disks.With SK-3 and SKD-11 disks,hardening the disk was effective in decreasing wear of both the pin and the disk.The results indicated that a counterpart material which had a fairly hard surface and developed a thin,adherent transfer film was essential to obtain good tribological performance.Addition of SUS304 to the composite improved strength,and also improved tribological performance when slid against an Si3N4 disk.The composites,with appropriate counterpart materials,have potential high temperature vacuum applications.
