Lubricated rolling wear studies of SiC-whisker (SiC{sub w}) reinforced Al{sub 2}O{sub 3} composites and monolithic Al{sub 2}O{sub 3} against M2 tool steel were conducted using a cylinder-on-cylinder apparatus. The composites wore considerably less than Al{sub 2}O{sub 3}. The wear of the tool steel against the composites was also considerably less than against Al{sub 2}O{sub 3}. Microfracture occurred on a smaller scale in the composites than in the Al{sub 2}O{sub 3}. This was attributed to the differences in microstructure and fracture toughness. The worn surfaces of the steel and the composites were polished, possibly due to fine, hard wear debris circulating with the lubricant to the contact area.
