Modification of wear-resistant coatings of the Fe-Cr-C system with spherical tungsten carbide WC-W₂C

Abstract

The article describes the production procedure, studies the structure, and determines the properties of new wear-resistant coatings of the Fe-Cr-C system intended for hardening the working bodies of agricultural machines. To increase the wear resistance and give new consumer qualities to such coatings, they were modified with spherical tungsten carbide WC-W2C -spherorelite. It is shown that the introduction of the complex (WC-W2C+B4C) into the basic charge allows increasing the hardness of the deposited to 1000 … 1200 HV100, and wear resistance by 3.1 times in relation to the base material, and by 1.3 … 1.8 times in relation to the base (not hardened) material.
