The influence of biodegradable lubricants such as rape seed oil and some synthetic esters on tribological properties of aluminium-silicon alloy were studied at a mild operating condition with a pin-on-disk tribometer. It was found that the rape seed oil was inferior to the hydrocarbon oils and the synthetic esters in the friction and anti-wear properties. In addition, presence of double bond in acyl group of synthetic ester was detrimental to the friction and anti-wear properties. XPS analysis showed the boundary lubrication film containing aluminium soap on the surfaces with rape seed oil and the synthetic esters. The difference in tribological properties between rape seed oil and the synthetic ester may be due to the difference of mechanical properties of aluminium soap.
