Comparative studies on the wear resistance of modular milling cutters made of high-speed steel P18 with subsequent diffusion discrete oxidation are carried out. The paper considers physical and chemical regularities of formation of discrete diffusion oxidation, designed for hardening and wear resistance of high-speed cutting tools. The results of research of structure and properties of structural alloyed steels due to formation of discrete diffusion oxidation are presented. It is established that the technology of discrete oxidation allows to increase the wear resistance of complex profile cutting tools by 80...85 % in comparison with the traditional technology (TiCr)N.

Specialized stainless 09Kh17N7Yu steel becomes more usable in various fields of mechanical engineering due to its unique properties, but recommendations for parameters of the cutting mode and for rational tool materials are out of date. Due to this, excessive consumption of tool materials is observed. It is necessary to develop new recommendations with adaptation to high-performance processing on CNC machines. The recommendations of foreign tool manufacturers are insolvent for choosing their tool, because there are no direct foreign analogues of this steel. Researches are carried out to reduce the consumption of hard tool alloys of VK, ТК and ТТК groups, as well as number of foreign tool materials. The possibility of using VК8 alloy with coatings for turning by removable standard hard alloy plates is established. Rational coatings are chosen from the number of known coatings. New coatings are developed for specified operating conditions

Considered is the qualification feature of dimensional abrasive jet processing when cutting masked semiconductor substrates on a silicon base into round discs-crystals. This approach is used when dividing stacked substrates into crystal disks, which have a tapered side surface and, accordingly, a difference in the size of the diameters at the ends of the crystal. The process of the formation of crystal disks is described and the dependence of the crystal taper on the masking method and the parameters of jet-abrasive processing is revealed. It is shown that crystal disks of the same size with a minimum taper can be obtained by increasing the processing time, manufacturing masking disks from wear-resistant materials, and choosing the optimal distance between the masking disks taking into account the substrate thickness.

It is shown that vibroabrasive treatment of hardened titanium alloy specimens contributes to an increase in their durability. This effect is explained by the removal of a defective surface layer containing microcracks and subject to the influence of residual tensile stresses. It is shown that the proposed stage of vibro-abrasive processing with ceramic granules makes it possible to almost completely remove iron introduced after vibro-impact surface hardening, which makes it possible to exclude the operation of etching in nitric acid from the technological process. The current state of research on durability in world science is briefly presented.
