METHOD OF FORMATION OF THE MICRORELIEF ON THE DETAIL SURFACE Russian patent published in 2007 - IPC B24B39/00 

Abstract RU 2297314 C2

FIELD: mechanical engineering; methods of formation of the two-level microreliefs.

SUBSTANCE: the invention is pertaining to the field of mechanical engineering, in particular, to the methods of formation of the two-level microreliefs. The method provides for rotation of the detail, its feeding and formation on its surface of the two-level constant microrelief combined in height by the vibrorolling of the grooves by the ball and the indenter. The grooves rolled by the indenter are placed between the grooves rolled by the ball. The grooves are made sinusoidal by the ball vibrorolling with the ball radius of Rb = l.5...2.0 mm with the effort of Рb = 160...500 N and by the indenter with the radius of Rind = 0.5...0.8 mm and with the effort of Pind =80... 250 N. At that the grooves rolled by the indenter are made with the smaller interval and the smaller height, than the grooves rolled by the ball. The technical result of the invention is the increased microhardness of the surface, the residual stresses of compression are formed in the surface layer, the wear resistance is increased, the treated surface the support length and support area are increased.

EFFECT: the invention ensures formation of the residual stresses of compression in the surface layer, the increased microhardness of the surface, its wear resistance, the support length and support area of the treated surface.
