摘要：
This paper compares the wear characteristics of hypereutectic aluminium-silicon alloys processed using two different routes: the more recent spray-deposition technique and the conventional casting process. Unlubricated pin-on-disk wear tests revealed that the spray-deposited alloy has a better resistance to wear than its conventionally-cast counterpart. It is suggested that the increased hardness and the uniform distribution of the fine second phase in the spray-deposited alloy endowed it with a better wear resistance compared to the conventionally-cast alloy over the range of sliding conditions investigated presently.
