This paper discusses results of research concerning the microstructure and scuffing resistance of HVOF sprayed WC- 12Co nanostructured and conventional coatings under dry friction conditions. The observations were carried out by means of a Falex type tester. It was found that HVOF sprayed nanostructured WC-12Co coatings showed the most homogeneous structure, the greatest scuffing resistance and the highest hardness.
