Effect of sillimanite particle reinforcement on dry sliding wear behaviour of aluminium alloy composite

摘要: Abstract The effect of sillimanite reinforcement on the dry sliding wear behaviour aluminium silicon alloy (BS LM6) composite was investigated using a pin-on-disc test machine. specimens were prepared liquid metallurgy technique and 10 wt-% particles incorporated in matrix alloy. Sliding tests conducted at applied pressures between 0.2 1.6 MPa speeds 1.89, 3.96 5.55 m s-1. also tested under identical conditions order to enable comparison. It observed that reinforced exhibited lower rate than Increase load increased while increase speed reverse effect. seizure pressure significantly higher temperature rise near contacting surface coefficient friction less SEM microgr...
