FIELD: metallurgy.
SUBSTANCE: layer of nano composite structure containing silicon oxide dissolved in litol is applied on parts of metals or alloys. Further, the layer is radiated with electro-magnetic field of high frequency f=3÷5 MHz during specified interval of time t=5-15 seconds chosen depending on geometric dimension of parts. Owing "to skin-effect" the surface layer of treated part is heated to temperature within the range from 700° to 900°C. Dislocations of the surface layer are blocked with positive ions of heavy metals by the method of electro-mechanic implantation when direct electric current is transmitted through the contact a part-implanted strengthening metal.
EFFECT: obtaining nano structured wear resistant surfaces designed for strengthening surface layer of machine parts of cylinder form and threaded surfaces.
