Nanostructured cermet coating was sprayed from agglomerated nanostructured WC12Co powder feedstock by means of hypersonic spray process (HVOF). Grains of tungsten carbide nanopowder were analyzed by scanning electron microscope (SEM) and transmission electron microscope (TEM). Investigations revealed that grains of powder consist of nanoparticles. Nanostructured sprayed coating was observed by SEM. A denser coating structure with higher hardness compared to conventional coating was observed. Dry abrasive rubber wheel tester was applied to estimate wear resistance. These tests show that nanostructured tungsten carbide have got better wear resistance.
