The Temperature of Sliding Surfaces.
Abstract
An analysis is proposed for estimating the average interface temperature rise during sliding of two surfaces. The basic model includes surface topography statistics, frictional conditions, the effective surface hardness, and thermal parameters. In 75% of the material pairs studied, the analysis gives fairly good results. It appears applicable to either dry or lubricated surfaces. In particular, good correlation was obtained with the following material pairs: Brass-steel, cast iron-steel, graphite steel, tungsten carbide-steel, babbit-steel, titanium-magnesium, nickel-magnesium, and graphite-aluminum. Sliding speeds ranged up to 100 in/sec, average contact stresses typically were in the 25-250 psi range, and temperature rises up to 200F were observed. (Author)
