The relationship between the temperature and the lubricating properties of an organocopper compound used as a lubricant additive has been studied on steel‐steel rubbing pairs. The results showed that the organocopper compound significantly reduced both the wear and the friction of steel balls for different test temperatures, but that there is a distinction between the friction critical temperature and the wear critical temperature. Results showed that the organocopper additive could improve both the friction critical and the wear critical temperature of a mineral oil. For example, the friction critical temperature increased from 50 to 220°C and the wear critical temperature from 110 to 290°C. Micrographs of the wear scars at different temperatures were used to investigate the lubricating film's temperature characteristics.
