Method of manufacturing a Co-Cr-Mo-based alloy and Co-Cr-Mo-based alloy

摘要

Cr: 25~35% by weight and, Mo: and 3 to 8% by weight, Zr: 0~0.1 wt%, Si: 1 wt% or less, Mn: 1% by mass or less, C: 0.01~0.3 wt%, N: 0.08~0.8 group consisting wt% and a dopant comprising at least one be more selective, the balance of the raw material consisting of Co, the total rolling reduction to produce perform hot working so that at least 60% at 1000 above, the biomaterial high safety, high strength, high ductility, Co-Cr-Mo-based alloy and a manufacturing method thereof having high fatigue strength.
