Tribological Behaviour of Ceramic Coatings Formed on Titanium Alloy through Miro-Arc Oxidation Technique

Abstract:

In the present work, the wear behaviour of coatings produced on Ti-6Al-4V alloy by micro-arc oxidation method was studied. The wear tests were performed using a pin-on-disc wear machine under dry sliding conditions. It is found that the MAO coating can efficiently improve the wear-resistant performance of Ti alloy in the test range of this paper. The coated samples demonstrated wear rates up to 5-12 times lower than that of the uncoated substrates tested. The wear behaviours are deeply characterized by the variations of coating structure and composition.
