In this paper, the tribological properties of plasma-sprayed coatings are studied. Plasma sprayed coating enhances the surface properties of the substrate material such as corrosion resistance and mechanical properties. Friction in rubbing surfaces causes wear and loss of energy. One way of improving surface resistance to wear is by applying coatings. Al 6061 alloy finds wide applications in the fields of automobile, aero-space, domestic etc.; however it is a soft material with poor wear

Using pin-on-disc tribometer, the tribological behavior of Al6061coated sample was studied under dry sliding conditions. The objective is to establish a correlation between dry sliding wear behavior of Al6061 and Al 6061 as coated with same wear parameters. The effect of wear parameters like applied load, sliding distance and speed on the sliding wear were studied. The results showed that the extent of variation of wear of coated specimen was very minimal and lesser compared to uncoated Al 6061 with increase in load, speed and sliding d instance.
