Friction and Wear Behavior of GT35 Cemented Carbide at High Temperature |
| |
| Abstract: | The friction and wear properties of GT35 cemented carbide were investigated by using ball-disk high temperature friction and wear tester. The friction and wear characteristics of GT35 cemented carbide were studied. The friction and wear behaviors of GT35 cemented carbides at different temperatures and friction radius were analyzed. The results show that the friction coefficient and specific wear rate of GT35 cemented carbides increase with the increase of temperature under constant normal load, and the friction coefficient and specific wear rate increase with the increase of friction radius. |
