The paper discusses the methods of erecting sunk wells and pile foundations, which consist in regulating frictional forces soils: lowering along lateral surface when sinking increasing foundations. developed method provides for application two types effective antifriction coatings surface: cutting edge structure above ledge. At same time, coefficients reducing friction by these various soils ha...

Avinit duplex technologies have been developed, combining N plasma nitriding of finished high-precision parts with subsequent application superhard antifriction coatings in a single technological process Due to the absence brittle layer on nitrided surface after precision nitriding, preservation original geometric dimensions that do not require further mechanical refinement, and compatibility p...

This article investigates the impact of manufacturing technology on structure, mechanical, and tribological properties new antifriction composite materials based R6M5 high-speed tool steel grinding waste. The characteristics composite’s structure formation its after use established technological modes, including waste regeneration, were illustrated. It was demonstrated that such is capable ensu...
