Question

10. An engineer is designing a total hip implant. She intends to make the femoral stem out of titanium because it forms a good interface with bone. However, since titanium does not have optimal wear properties she intends to make the ball component out of stainless steel and attach it using a press fit. Should she be worried about corrosion? If so what types of corrosion could take place?

Answer 1

Yes. She should be worried about corrosion. The 18-8 stainless exhibits intergranular corrosion due to high (0.08%) carbon content and gross pitting due to low molybdenum content.
