Room temperature sliding wear behavior of Ti6Al4V: A review

Abstract

High strength-to-weight ratio, high temperature stability, and bio-compatibility makes Ti6Al4V alloy an interesting choice for aerospace, automobile, chemical, and bio-medical industries. In spite of the several attractive properties, the application of the alloy is restricted in sliding interfaces. As a result, many studies, involving surface modifications of the alloy or the tribo-pair in general have surfaced for improvement in tribological properties. The details of tribological behavior of un-modified Ti6Al4V alloy in various operating and environmental conditions, can act as an initial data for the future researches aimed at improving its tribological properties. Thus, the present review is an attempt to put together the studies conducted to evaluate the sliding wear behavior of Ti6Al4V in both dry and lubricated condition at the room temperature. © 2021 Author(s).
