Al-Sn-Si alloys%wear%friction%tribology characteristic
Tribological characteristics of new series of Al-Sn-Si alloys were investigated by means of pin-disk types of wear testing machines, OM, SEM and EDAX. Rules about the influence of Sn, Si content and load on the friction and wear characteristics of the alloys were ascertained. The friction factor and wear rate of the alloys decrease with increasing Sn content, the wear rate decreases but the friction factor varies hardly with increasing Si content. The friction factor of the alloys increases slightly and the wear rate increases observably with increasing load in the range of 10-80 N. The wear mechanism of Al-Sn-Si alloys consists of 'plough' action and abrasive wear below 30 N; the adhesive and delamination mechanism are shown in the range of 30-80 N. The tribological characteristics of Al-Sn-Si system are superior to those of Al-Sn or Al-Si systems due to their "peritectic-type" island-shape microstructure of Si surrounded with Sn.
