Abstract : An examination was made of the effect of temperature and the nature of the filler (molybdenum disulfide, boron nitride, barium sulfate, ground coke, talic, soot, or colloidal graphite) on the coefficient of friction and wear of 'Fluoroplast' (poly(chlorotrifluoro ethylene)) while undergoing a witer-lubricated friction process. In general: (1) wear decreases with increasing filler content (up to a limit); (2) wear increases with increasing water temperature; (3) the coefficient of friction (mu) increases as temperature increases; (4) mu decreases with increasing specific pressure; and (5) mu decreases with increasing speed of sliding. Under the test conditions, MoS2, BN, BaSO4, and coke proved improve the wear resistance to a greater extent than the other fillers.
