Effect of static cooling technology on the friction and wear properties of titanium alloy

Abstract:

To investigate the tribology properties of titanium alloy in static cooling condition,the friction and wear experiments of YG8/Ti6Al4V were carried out on high speed friction and wear test auxiliary device designed by ourselves.The experimental results showed that static cooling technology could effectively decrease the friction coefficient of YG8/Ti6Al4V friction pair,restrain the wear of friction pair,and improve the worn surface quality of Ti6Al4V.SEM observation indicated that in high speed friction,the main wear mechanism was adhesion wear and shedding accompanied with microcracks.Compared with that in dry condition,adhesion wear was less under static cooling condition.The turning test results demonstrated that the anti-friction effect of static cooling technology could effectively restrain tool wear and improve tool life.
