Abstract
The friction and wear characteristics of newly developed stainless steel with dispersed precipitations, which was designed for improving friction and wear characteristics, were investigated with ring-on-disk test apparatuses under non-lubricating condition in air and in vacuum. The friction and wear behaviors were compared with those of JIS SUS420J2 stainless steel. Both friction coefficient and wear amount of the stainless steel with dispersed precipitations were smaller than those of SUS420J2. The extent of transference of wear debris was comparatively small in case of the stainless steel with dispersed precipitations. The stainless steel with dispersed precipitations had the superior friction and wear characteristics.
