Abstract

The present study was conducted to understand effect of ceramic reinforcement, normal load and heat treatment on abrasive wear rate of aluminum metal matrix composite. A statistical approach: design of experiment was used for the present investigation. A mathematical model was developed relating reinforcement and applied load on the abrasive wear rate of the composites. Experiments were conducted on the both as-cast and heat treated condition. The developed model was checked for adequacy by regression analysis and analysis of variance. The result shows that Ceramic reinforcement will improve the wear resistance of the matrix material. The Predicted model yields an error of 0.028 and 0.0241 for the as-cast and heat treated condition respectively, which is indicated as standard error of estimate.
