Analytical review on the definition of a rational method of hardening of the surface layer of cemented carbide cutting tools. The conditions of work and key The causes of loss of efficiency of cutting tools. It is shown that the presence of hubs stresses affect the premature deterioration and destruction of cutting tools. Given exist-ing techniques to improve performance characteristics of the cutting blade of tools and discusses their advantages disadvantages. Discussed ways of strengthening such as wear-resistant coatings, the introduction of the near-surface region of any solid ones la, heat treatment with highly concentrated heat sources and doping with laser treatment, the impact of the electron beam on the surface of the carbide inserts. On the outward-effective modification of cutting tools by controlling structural and phase composition of the surface layers. Presents one of the most promising methods for modification of hard alloy. The influence of pulsed electron-beam irradiation is shown in the reduction of the friction coefficient and the Research Institute of the cutting force, a significant increase in tool life.
