Simulation Analysis of Friction and Wear of New TiAl based Alloy Joint Bearings

Abstract

The joint bearings are special kind of sliding bearings, which have excellent load bearing, impact resistance, corrosion resistance and so on, they have been widely used in many engineering fields such as heavy machinery, aerospace, vehicle engineering [1]. In actual work, friction and wear are the main failure modes of joint bearings. Therefore, improving the friction and wear characteristics is great significance to joint bearings. TiAl-based alloys have high specific strength, low density, good corrosion resistance and good mechanical properties such as high temperature creep resistance under high temperature conditions [2, 5]. TiAl alloys are considered to be the most promising new generation of alloy materials [6]. This makes it possible for TiAl-based alloys to be ideal joint bearing materials under high heavy load conditions. Here, using workbench to simulate a new type of TiAl-based alloy material with strong bearing capacity and good friction and wear characteristics under certain conditions, and compared with the joint bearing of common material.
