Properties of polyol esters--lubrication of an aluminum silicon alloy

Tribology Transactions | July 1, 1997| | Copyright

The chemical and physical properties, of lubricants significantly affect their performance in industrial applications where aluminum is used as a sliding material. The inertness of aluminum contributes to its poor wear resistance. The wear characteristics of a series of polyol esters were evaluated in terms of their chemical structure for the lubrication of an aluminum-silicon (Al-Si) alloy using a pin-ondisc-type wear tester. The molecular structure and the number of acid groups of the polyol esters strongly affected their ability to lubricate the AISi alloy. The wear and scuffing ...
