“…The results show that the friction stability decreases with the increase of the ambient temperature, the friction and wear mechanism changes continuously. Amit Roy et al [27] focused on developing suspension plasma sprayed (SPS) tantalum oxide coatings and evaluating their tribological behavior from room temperature to elevated temperatures. The tribological results illustrated that the friction coefficient of the tantalum oxidecoating slightly decreased from 0.9 at 25℃ to 0.8 at 300℃ and the wear rate was reduced by more than 50%.…”
