| Experiments were carried out to investigate the effect of various casting processes such as sand casting, chill casting and ESR, and also of nickel addition on the structure and sliding wear properties of Al-Sn alloy containing up to 20% tin. The results obtained are as follows; 1) Addition of nickel to the Al-Sn alloy produced by sand casting and ESR was effective to refine tin particles, while there was no structural change in chill cast alloy. 2) The wear resistance of the alloy produced by ESR was superior to that by sand casting and chill casting. The wear resistance varied with sliding conditions, but better wear resistance was achieved with continuously networked tin structure. 3) In the sliding wear of Al-Sn alloy, abrasive and adhesive wear were occured, while oxidizing wear was not recognized, resulting an increased sliding speed raised the wear amount. 4) In the wear test of Al-Sn alloy, the average size of wear debris and the wear amount increased with increasing sliding speed, and both of them were also found to be in proportional. |
