FIELD: metallurgy. ^ SUBSTANCE: detail is preliminarily subject to mechanical operation by turning on turning machine with creating on its surface of rough edges in the form of combs with the profile of trapeziform shape with height 10-20 mcm, width at the basis 25-35 mcm and inclination of side walls 5-10 with following influence upon the detail's surface by indenter, normally oscillated with supersonic frequency. ^ EFFECT: formation of nano-crystalline structure in surface coating and substructure in underlying metal, increasing of wear resistance, corrosion stability, reliability and durability. ^ 10 dwg |
