摘要：
A systematic study on the effect of heat treatment on the structural properties of tungsten carbides coatings deposited by RF magnetron sputtering on steel substrate (XC70) was carried out. These coatings were subjected to heat treatment in vacuum at various temperatures ranging from 500 to 1000 A degrees C for 25 min. Structural analysis of the as-deposited and heat-treated coatings was performed by means of X-ray diffraction (XRD) and optical microscopy. The XRD analyses indicated the presence of nanocrystalline grains with (222) preferential orientation. The grain size varied from 8 to 15 nm. The presence of two different phases WC and W2C was observed in the coatings heat treated at 1000 A degrees C. The effect of the annealing temperature on the surface morphology of the coatings was studied using optical microscopy.
