Purpose of the development: The technology allows to form nanocrystalline structure of the working surfaces of parts machines. The technology is easy to implement on turning, round and surface grinding machines, slightly to modernize without large capital investments

Recommended application field: Technology can be used in food processing, machinery, coal and oil and gas industry to strengthen sleeves and pump shafts, rods of hydraulic cylinders, fingers pipelines and compressors, the end surfaces of gears and handling rings hydraulic pumps, work surfaces and paper cutting knives and other woodworking of flat and cylindrical surfaces.

Technical characteristic: Characteristics of the development: The technology is based on the use of high-energy friction. In the area of frictional contact workpiece and a special tool is an intensive firming heating of the surface layers of detail with speeds (105-106) K / s while the plastic deformation and rapid cooling. Such conditions allow dispersed structure and saturate the surface layers of different alloying elements of technological environments, served in the processing area. The thickness of the hardened layer on steels up to 100-800 m, microhardness 12.6 GPa, the roughness of the hardened surface Ra = 0,4-3,0 m. Depth and microhardness of the hardened surface layer and the surface roughness can be enhanced processing modes. The resulting surface nanocrystalline structures have low (0.02-0.04), the coefficient of friction Slip over wrought iron (0,16-0,18). They are characterized by high wear resistance, corrosion-erosion resistance and contact fatigue fracture.

Advantages over analogues: Benefits: The technology allows to form nanocrystalline structure on work surfaces machine parts, without changing the structure of the matrix material. The use of technology increases life of the machine parts in 2-3 times, while the complexity of 20-30%.

The development stage readiness: Ready for application

Technical and economic effect: Economic impact: - Increased service life of; - Reduction of material and energy costs; - Reduced maintenance costs. Technology has been laboratory-resource research and pilot testing by enterprises in Ukraine. 1. Patent number 42,154.
