Study of Small-Scale Friction at Elevated Temperatures

This paper presents some preliminary results obtained from small-scale friction measurements from 25°C to 200°C on fused silica and 1018 low carbon steel surfaces. Friction transition phenomena were observed on the surfaces of fused silica and 1018 low carbon steel. The friction coefficient of the fused silica was found to be lower at higher temperature due to the material softening effect. However, the friction coefficient of the 1018 steel was found to be greater at high temperature which is likely the result of surface oxide formation.
