摘要

The friction behavior of resin-impregnated and non-impregnated graphite sliding against a cemented carbide in dry,oil,and water environments using a ring-ring configuration was investigated.Friction coefficients were recorded at various speeds.The results showed that the impregnated graphite exhibited much better friction properties under water or oil lubrication than non-impregnated graphite,and the impregnated graphite could remain in the stable friction regime under high pressure × velocity (pv).Based on scanning electron microscopy and Raman spectroscopy analyses,the different characteristics between impregnated and non-impregnated graphite were able to be attributed to the structure of the graphite and wettability of the lubricants.
