Abstract
The lubricity of lubricants including silicon oil with chlorobenzene group, cyclotriphosphazene derivative X-1P and perfluoropolyether (PFPE) for both steel/steel and steel/bronze sliding pairs were studied. Gel percolation chromatography was used to detect the tribopolymerization of the tested silicone oil. Chlorinated-phenyl and methyl terminated silicone oil (CPSO) showed excellent thermal stability, low temperature fluidity, and very low saturated vapor pressure. CPSO showed excellent tribological behavior for sliding pair of SAE 52100 steel/CuSn alloy, and was superior to perfluoropolyether in terms of friction-reduction ability and load-carrying capacity. Tribopolymerization was found after sliding of steel against CuSn alloy under lubrication of CPSO, with the formation of very high molecular weight polymer. Phosphazene (X-1P) as additive for PFPE is useful in reducing wear of steel/CuSn alloy sliding pair. This is an abstract of a paper presented at the 11th Annual Fuels and Lubes Asia Conference (Beijing, China 3/15-18/2005).
