1. Saturation of the matrix with tungsten and carbon during interaction of the matrix with grains of tungsten carbide eliminates the substantial difference in the wear resistance of hardening particles and the matrix of the composite material and secures the tungsten carbide grains in the material. 2. The tungsten diffusing from tungsten carbide alloys both components of the eutectic structure of high-chromium cast iron; no tungsten is found in dendrites of primary austenite. 3. Electroslag hard facing with use of high-chromium cast iron as the binder for grains of tungsten carbide makes it possible to obtain a composite material with high wear resistance and fairly high strength characteristics.
