Wear in machineries and parts are one of the major problems encountered in industrial processes. These problems along with corrosion lead to the development of surface engineering techniques that involves applying surface coatings to components to obtain composite material with tribological properties unattainable by base material alone. In the present paper, DLC and WC coatings are produced on AISI D2 steel by Physical Vapor Deposition (PVD).The samples are characterized with tribological test. The applied load is taken as 25 Newton, and sliding velocity as 0.5 m/s. Samples with DLC coatings display less friction and good hardness.

These problems along with corrosion lead to the development of surface engineering techniques that involves applying surface coatings to components to obtain composite material with tribological properties unattainable by base material alone. In the present paper, DLC and WC coatings are produced on AISI D2 steel by Physical Vapor Deposition (PVD).The samples are characterized with tribological test. The applied load is taken as 25 Newton, and sliding velocity as 0.5 m/s. Samples with DLC coatings display less friction and good hardness.
