Короткий огляд (реферат): The study of the wear resistance of cutting tools is of paramount importance due to their wide application in the machining of parts in mechanical engineering and other branches of technology. Therefore, the problem of increasing the strength characteristics and operability of cutting tools is important. The paper presents the results of experimental studies of the wear resistance of socket mills made of high-speed steels and hard alloysin the processing of hard-to-process structural chromium steels. The method of experimental research of wear resistance is generated. The technology of hardening the cutting teeth with a wearresistant coating using the PVD method has been developed. The influence of the structure of a composite coating based on titanium nitrides and carbides on the mechanical characteristics and working capacity of the cutting tool is shown. The results of an experimental study of the effect of hardening coatings of the cutting teeth of socket mills on wear resistance are obtained. The nature of wear and brittle destruction of the working surfaces of the tool under intermittent cutting conditions and the effect of high-strength coatings on the thermal and stressstate of the cutting edge in the contact zone are investigated. The dependences of the resistance of the cutting teeth of socket mills on the cutting speed and infeed during the processing of workpieces made of hard-to-process chromium steels are given. X-ray spectral analysis of the chemical composition of the surface layer of the cutting plates was performed. The structure of the wear surface and brittle fracture of the cutting teeth is presented
