Effects of the moisture content in high purity gas on friction characteristics of carbon fiber filled PTFE was investigated by pin-on-disc tests. Results showed that the reduction of moisture content in gas tend to decrease friction coefficient. Analyses of transfer films by XPS, FT-IR, Raman spectroscopy, and laser microscopy showed that a part of the transfer film consisted of thin and smooth carbon layer and the area of smooth layer became larger with lower moisture content in gas. Therefore, the trace moisture might have some influence on the formation of the smooth carbon film.
