摘要: The influence on corrosion resistance of C45 carbon steel in chloride environment covered by coats of tungsten carbide and copper were examined. The coats were put on the surface of steel by electrospark method. The potentiodynamic polarization technique for corrosive investigations was applied. The topography of surface by scanning electron microscope (SEM) was observed. The most corrosion resistance was exhibited for steel covered by mixture of the 25% WC and 75% Cu nanopowders. The top layer of coating is not homogeneous and consists of copper, WC2, tungsten carbide and iron. The laser treatment modifies of the electrospark layer and influences on the correct it usable properties.
