Hard and thick ceramic coatings to protect titanium implants from wear

Sensitisation to immunologically active elements like chromium, cobalt or nickel and debris particles due to wear are serious problems for patients with metallic implants.

In this project, we tested the approach of using a hard and thick ceramic coating as a wear-resistant protection of titanium implants, avoiding those sensitisation and foreign body problems. We showed that the process parameters strongly influence the coating porosity and, as a consequence, also its hardness.
