摘要：

Repeated four-ball tests of squalane with or without organic sulfides have been carried out to investigate the relationship between the properties of surface films formed on the rubbing surfaces and the lubricating performance of several organic sulfides. With dibenzyl disulfide and dibenzyl monosulfide, friction was remarkably reduced and load-carrying capacity raised in the second run with the additive after the first run without the additive, presumably in which only an oxide film had been formed. In contrast, for diphenyl disulfide, the repetition of rubbing tests, each with additive, was effective. Electron Probe Microanalysis (EPMA), X-ray Photoelectron Spectroscopy (XPS or ESCA) and electron diffraction techniques have been applied to examine surface films formed during rubbing process. It was confirmed that the formation of surface films with the optimum composition of oxide and sulfide has brought about the excellent lubricating performance of these organic sulfides.
