Effect of Annealing Temperature on the Microhardness of Tungsten Carbide Coatings

Abstract

Tungsten carbides (WC) coatings have been deposited by RF magnetron sputtering onto steel substrate (XC70) temperature in the range of 500-1000 °C under vacuum for 25 minutes. The mechanical properties of WC were investigated by the measurements of microhardness by Vickers tests. We carried out microhardness tests with loads varying between 10 g and 1000 g, and the variations of the microhardness of our samples were followed as a function of the annealing temperature, the applied load and the penetration depth of the indenter.
