Electrotechnology and material processing

1. Restoration of metal-cutting tools - (the restored tools have twice as long service life as new ones)
   Theme of development: Electrotechnology and material processing

2. Examination of chemical composition and possible reasons of its variation in VAR 112D type relay models - The reasons for variation of the properties of current relay contacts used in railway transport have been established.
   Theme of development: Electrotechnology and material processing

3. Liquid metallic contact for current collection - (no toxic or explosive components such as mercury and sodium-potassium alloys are used; the ecological state of shops at non-ferrous metallurgy and machine-building enterprises is improved)
   Theme of development: Electrotechnology and material processing

4. Electrochemical machining of parts with complex geometry - (Research, designing and experimental technological works were performed to establish the hydrodynamic conditions for feeding the electrolyte solution to the working area with the use of П-shaped multiplace tool electrodes, which provide the maximum loading of the technological current source of the ЭХФ А-1 machine with the treatment area of 100 cm². Machining attachments were made to the device for series production of turbine blades of the 10^th stage of the ТВ2-117А compressor rotor with productivity 8 blades per hour.)
