Effect of thermal oxidation and carbon concentration on Co-Cr-Mo alloy in enhanced corrosion protection

Surface modification of metallic implants is often required to facilitate positive interaction between the implant and the surrounding hard tissue. In the present study, an oxide layer (Cr2O3) was successfully created on a Co-Cr-Mo alloys substrate by using thermal oxidation technique in atmospheric...
