- 摘要：
PROBLEM TO BE SOLVED: To provide a porous Co-based alloy sintered coating material which has an enough adhesion strength to biological tissues specially when it is used for implantation materials such as a material for artificial hip joints, and also which can be effectively prevented from being brokendown inside a sintered coating layer or between the sintered coating layer and a base material, by forming a Co-based alloy sintered layer on the base material with a prescribed composition and condition.
SOLUTION: The porous Co-based alloy sintered coating material has the base material comprising CoCrMo and the porous Co-based alloy sintered coating layer which is formed on the base material, has a composition containing 20-34 mass% of Cr and 1-10 mass% of Mo, also containing total 0.05-5 mass% of one or more kinds of elements selected from the group consisting of Ti, Zr, Nb and Ta, and the balance comprising essentially Co, and of which the porosity is in the range of 5-40%.
