Abstract
Currently, carbide cutting tools are mainly used for processing blanks of machine parts. Increasing the working life of carbide plates is one of the urgent tasks in mechanical engineering. The paper proposes to increase the working life due to the complex modification of the working surfaces of the carbide tool. Modification of the tool surface is proposed to be carried out on the basis of electron beam alloying with an alloy based on niobium and hafnium, followed by the application of a wear-resistant coating of titanium aluminitride.
