Friction and Wear Behaviour of Borided Ti6Al4v Alloy Sliding Against Al<sub>2</sub>O<sub>3</sub> and Si<sub>3</sub>N<sub>4</sub> Balls in Water

Abstract

This study focuses on tribological performance of as-received and borided Ti6Al4V alloys against ceramic counterfaces (Al2O3 and Si3N4 balls) in water. The wear mode of the alloy changed from ploughing to polishing by achieving a remarkable reduction in wear loss upon boriding. On the borided surface, the destructive action of the Si3N4 ball was very limited, when compared to that of the Al2O3 ball.
