Abstract

Lubricated and unlubricated sliding wear tests were carried on sintered iron based ternary alloys produced by powder metallurgy technique. The detailed experiments were carried out on Fe20Al20Al, Fe15Al15Cu and Fe(without alloying elements). Friction and wear behavior of solid lubricant at four different sliding speeds (1, 1.5m/sec) has been compared with unlubricated sliding condition. Sintered iron based ternary alloy Fe20Al20Cu under lubricated condition shown reduction in mass loss compared Fe15Al15Cu and Fe(without alloying elements) at all sliding speeds. Friction coefficient reduces with increase in sliding speeds for all the conditions. This could also be due to sliding resistance offered by lubricant coated samples with predominant asperities interaction. Sintered iron based ternary alloy Fe20Al20Cu under lubricated condition samples also generated lowestfrictional temperature compared to other conditions.
