Abstract.

For wear demanding applications, the coatings, consisting of WC in the nickel-based alloy are often used due to their excellent properties. Nevertheless, there are still limits of these coatings, mainly deterioration of tungsten carbide due to heat load during laser cladding. The suppress the limits, a new type of coating material, consisting of the (TiW)C1-x in nickel-based alloy, was designed. The goal of this study is to compare the microstructure and mechanical properties of new (TiW)C1-x based coating with a usual WC-based coating to confirm its improved behaviour.
