Creating Oxide Interlayer Through Thermal Oxidation Improves Adhesion Strength Of Hydroxyapatite Coating on Co-Cr-Mo Substrates

Creating Oxide Interlayer Through Thermal Oxidation Improves Adhesion Strength Of Hydroxyapatite Coating on Co-Cr-Mo Substrates

Improvements to the adhesion strength of hydroxyapatite (HA) coat by creating an oxide interlayer on cobalt-chromium-molybdenum (Co-Cr-Mo) substrate was assessed in this study. The amorphous HA films were crystallized by sintering HA at temperatures ranging from 550°C to 750°C for 1 hour. SEM and X-...
