【 摘 要 】
The Al- nano TiO2 composite processed powder metallurgy and wear behaviour was experimentally investigated on aluminium with combined nano TiO2 weight percent reinforcement of 4%,7% and 10% at different sliding velocity of 1.5 m/s,2.0 m/s,2.5 m/s and different normal loads of 10N,30N,50N. The effect of specific wear rate and co efficient of friction optimised by response surface method. The results predicted by the developed model are concurring well within the measured values. The correlation co-efficient of model, regarding the specific wear rate and co efficient of friction, were about 0.96 and 0.94 respective with conform the degree of accuracy of the mathematical model. The optimal condition attain the minimum specific wear rate and co-efficient of friction at sliding velocity 2.04 m/s and Normal load 13.5 N with Al- TiO2 10% weight. The predicted value of specific wear rate 1.08e-7 and co efficient of friction 0.31 respectively.
