Wear and Breakage Resistance of Hard Alloy Coatings Strengthened with Tungsten Carbide

详细

An increase in the wear resistance of soil cultivating equipment components by applying a hard-alloy coating is often used in practice. The good wear resistance of hard alloys is provided, in particular, by the presence of tungsten carbide within them. However, a lack of evaluation of the resistance of these alloys to breakage and life under operating conditions limits their extensive propagation (alongside cost). Results are given in this work for laboratory and operating tests of hard alloys with added tungsten carbide (in combination with hard alloys based on iron and nickel) on wear resistance, and the alloy breakage mechanism with plasma surfacing on soil cultivating machine tool components is evaluated.
