The necessary and sufficient properties of carbide substrate multi-coated for cutting tool

The paper presents the results of studies of the complex effect of the properties of carbide substrates and composite coatings on the tool wear resistance in the treatment of high-temperature chromium-based alloys. Rational use of a hard alloy whose mechanical properties make it possible to fully realize the properties of the coating. This is not realized at low values of strength and (or) heat resistance of a hard alloy. Exceeding the strength and heat resistance beyond the necessary for the implementation of the properties of the coating is superfluous.

Keywords: carbide substrate, multilayer composite coating, tool wear resistance.
