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.
