The hybrid metal matrix composite coating has found wide spread applications in the field of aerospace and automobile industries. In the present work the Al7075 is used as the major material and Gr micro particles along with nano TiO2 particles are reinforced in the composite material. The influence of wear parameters on the wear rate is calculated by Taguchi L9 array. Normal load, speed and distance are considered as the three parameters in the three levels. Further work is concentrated on the influence of percentage of nano particles in the composite and wear rate and hardness are evaluated. The results reveals that an increase in the wear resistance.
