Abstract

The bronze-alumina-silver composites were prepared by powder metallurgy technique (P/M). The tribological properties of composites sliding against AISI321 stainless steel pin were studied by using a pin-on-disk test machine under sea water condition. The silver showed the good lubricating effect in sea water. The addition of alumina improved the hardness and wear resistance of composites. The friction coefficient of bronze-alumina-silver composites increased with the increase of Al₂O₃. However, the specific wear rate of composites decreased with increasing Al₂O₃. Bronze-2wt% Al₂O₃-7wt% Ag showed the best tribological properties under sea water condition, especially, at the high loads and sliding speeds. The composites showed different wear mechanisms during the sliding process. Sea water showed the lubricating effect due to the presence of corrosion products on the worn surfaces.
