摘要

The performance of lubricants and additives was studied through simulated ball on disc experiments on aluminum alloys AA3003 and AA5182. Experiments covered five lubricant base oils with two additives at two additive concentrations. Comparison of lubricants was carried out based on measurements of the coefficient of friction (COF), surface damage and lubrication failure temperature. With lubricant applied during the cold rolling process, a protective layer containing carbon and oxygen forms on the alloy surface; the performance of lubricants is affected by both additive type and additive concentration. Lubricants' anti-wear property is sensitive to changes in additive concentration; that is with an increase in additive concentration, the wear decreases. For lubricants' anti-friction properties, only fatty alcohol shows a decrease in coefficient of friction when the additive concentration increases. With lower concentration of additive, higher lubrication critical temperature was observed. Generally, coefficient of friction is insensitive to aluminum material changing.
