| Abstract: | Ni-W alloy coatings were prepared on the steel substrate at the temperature of 60°C. The content of tungsten in coatings was increased with the growing cathodic current density. The increase of the corrosion resistance of Ni-W alloy coatings with the rising content of tungsten was confirmed by the measurement of anodic polarization curves. Annealed coatings showed better antioorrosion properties than the non-annealed ones. The properties of annealed coatings including their corrosion resistance depend on the tungsten content, too. |
