Fatigue response of porous coated titanium biomedical alloys

The effect of plasma electrolytic oxidation coatings on the fatigue properties of Ti6Al4V and Ti6Al7Nb alloys under physiological conditions (Hank’s solution at 37 °C) has been investigated. The oxidized Ti6Al7Nb alloys showed an improved fatigue behavior as compared to oxidized Ti6Al4V alloys, irrespective of the coating thickness.
