PROCEDURE FOR PRODUCTION OF SURFACE NANO COMPOSITE LAYER ON PARTS OF METAL OR ALLOYS

摘要

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=35 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 900C. 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. ^ 3 cl, 3 ex, 4 dwg
