Özet
The effect of the size of initial particles of WC – 12% Co powder on the microstructure and mechanical properties of coatings plasma sprayed onto a substrate from steel Nitronic 50 is studied. The microstructure of the coatings is investigated by scanning electron microscopy and x-ray diffraction. The microhardness and the wear resistance are determined. It is shown that the coatings deposited from the fine powder have greater thickness and almost twice lower porosity than the coatings from the coarse powder. However, the plasma sprayed coarse powder undergoes less decarburization. The coating from WC – 12% Co raises the surface hardness and wear resistance of Nitronic 50 by a factor of 6 – 7.
