Determination of the efficiency of high-entropy cutting tool materials

Abstract

Modern approaches to determination of the durability of cutting tool materials taking into account the effect of their entropy, Thermo-EMF, and the functional relationships between them are presented. It is confirmed that the tribological properties of complex alloyed high-speed steels and experimental cemented carbide hard alloys (ECCs) with modified cobalt binder as high-entropy materials can be improved. The results of a study of wear resistance, oxidation resistance, and optimum cutting conditions of ECCs are presented.
