摘要：

This study aims to elucidate the synergy effects of the sigma phase and carbide on the wear behavior of low-carbon (LC) and high-carbon (HC) cobalt-chromium-molybdenum (CoCrMo) alloys, by using pin-on-disc tests under Hanks' lubricated conditions. Fractured or torn-off sigma-phase precipitates were observed to be the main reason for abrasion for both LC and HC alloys. Carbides were torn off at the initial high contact pressure to form pitting; sigma-phase precipitates around the pitting were uprooted and led to micro cracks, which is considered as surface fatigue of HC alloy. In contrast, strain-induced martensite observed on the worn surface was contributed to the increase of hardness and abrasion resistance of LC alloy.
