FRICTION AND WEAR AT ELEVATED TEMPERATURES
Abstract
Measurements were carried out of the friction coefficient as a function of temperature using surfaces of stainless steel covered by low melting metals and non-metals applied in powder form. Some work was also done with a few other metal and non-metal surfaces. In cases where the interaction between the low melting substances and sliding surface is high, as revealed by the occurrence of wetting, the friction reaches a peak just below the melting temperature of the substance, and then drops to considerably lower values just above the melting point. The peak below the melting temperature is associated with the formation of large adhering fragments of the low melting substance on the sliding surface. When there is no wetting, the low-melting substance has, either below or above its melting point, essentially no effect on the friction.
