The process of manufacturing semiconductor components for the production of microwave diodes is considered. Scientifically based recommendations are presented for the separation of relatively thick, up to 1.5 mm, stacked silicon-based semiconductor substrates by the so-called sandblasting method, based on masking and pneumatic jet cutting of the substrate with micro abrasive powder. It is described the masking method and the principals of setting of the operating parameters of the packaged substrate jet processing, which were tested with a positive result on a pilot industrial sandblasting plant currently used by a domestic enterprise.

The priority of the Russian scientific school in research new structures of parts from metal powders made using electrohydraulic processing is shown. Simultaneously with the achievement of new structures by means of stamping, powder parts are given the required shapes. In the manufacture of powder parts such as cups, the combination of cold forging and electrohydraulic processing opens up new opportunities in increasing the high density of parts at the stage preceding sintering, increasing the depth of the cavity, and reducing the wall thickness of parts. In particular, this makes it possible to make from not passed sintering semi-finished products thin slice for metallographic studies. This technology allows unlimited alloying of iron powder with powders of other metals and the manufacture of deep thin-walled glasses from unique powder steels.

It is shown that a new type of electrode is obtained during the process of electrospark doping of the aluminum alloy surfaces, the microstructure of which is a mechanical mixture consisting of grains of high-melting component surrounded by a thin grid of low-melting component, which makes it possible to obtain micro- and nanowires made of low-melting component in the coating and leads to a significant improvement of the wear resistance of the coating. If the specified proportions of the components of the electrode are changed, micro- and nanowires will not be formed in the coating.

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to its unique properties, but recommendations for parameters of the cutting mode and for rational tool materials are out of date.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.
