FUNCTIONAL MEMBER FROM Co-BASED ALLOY AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO2007043688
Kind Code:
A9
Abstract:
A Co-based alloy having a fundamental composition of Co-Al binary system containing 3-15% Al and having a lamellar structure wherein f.c.c. structure a-phase and ß(B2)-phase are superimposed on each other in layers, which Co-based alloy is modified so as to have a porous surface layer region effective for chemical retaining capability, sustained release, biocompatibility, etc. through selective removal of either the a-phase or the ß-phase from the surface layer. As a third component, at least one member selected from among Ni, Fe, Mn, Ga, Cr, V, Ti, Mo, Nb, Zr, W, Ta, Hf, Si, Rh, Pd, Ir, Pt, Au, B, C and P may be contained in a total amount of 0.001 to 60%.
