Tribological behaviour of Cu60Zr30Ti10 bulk metallic glass

Dry sliding wear of as cast and different annealed states of Cu60Zr30Ti10 bulk metallic glass was studied using pin-on-disc measurement technique. The relaxed metallic glass showed high hardness and excellent wear resistance. An inverse relation between the hardness and wear rate was observed for the as cast and annealed metallic glass. Coefficient of friction measured for all the above samples was found in a narrow range of 0.3–0.4 being less for as cast sample.
