Abstract
Tribological properties of rapeseed oil, polyolesters and hydrocarbon oils were studied for an Al alloy and Al alloy and a combination of Al alloy and cast iron with a pin-on-disk type tribometer. For a combination of Al alloy and cast iron, rapeseed oil showed the lowest friction coefficient throughout the run, and the highest anti-wear properties among the oils tested, meanwhile it showed the worst tribological performance for Al alloy and Al alloy. This is probably due to chemical wear followed by abrasive wear based on formation of excessive aluminum soap on the sliding surface.
