Wear of Typical Carbon-Base Sliding Seal Materials at Temperatures to 700 deg. F

Abstract

Wear and friction studies were made to show the effects on performance of temperature, type of mating material, and minor composition changes in typical carbon seal materials. Most data were obtained at a surface speed of 10,000 feet per minute, a load of 1000 grams on a 3/16-inch-radius specimen, and temperatures to 700 deg F. Wear of carbon seal materials increased rapidly with high temperatures. The effect of temperature on wear was reduced by using chromium-plated steel as the mating surface rather than stainless or tool steel. In general, the type of carbon and impregnation of the carbon seal material had little effect on wear compared with the effect of the mating metal.
