A tool for producing nanocrystalline structures by high-speed friction on the surface of machine parts, in which for the purpose of increase of the depth and microhardness of strengthened layer due to increase of the dispersiveness of structure and increase of durability of the tool fingers are made from the material with hardness HRC 52-55, for example, steel, and the number of fingers is selected from the ratio:,where D - outside diameter of disk, mm; d - diameter of fingers, mm. |
