FORMATION METHOD OF MOLECULAR COATING ON SURFACES OF PRODUCTS FROM METALS AND ALLOYS Russian patent published in 2013 - IPC F15D1/06 F17D1/16 

FIELD: machine building.

SUBSTANCE: method consists in formation on surfaces of a structured film by creating emulsion of surface active substances (SAS), dosing the emulsion to fluid medium; at that, as SAS, biologically and thermally non-decomposed compounds are used, which are chemically inert in relation to fluid media, for example film-forming amines; the above medium is heated to the temperature that is higher than fusion temperature of used SAS; products are cleaned from corrosion products and deposits; the product is placed into fluid medium; electromagnetic field is created by introducing to fluid medium of an electrode; the electrode is connected to one pole of a current source, and the product from metal or alloy is connected to the other one; temperature and electromagnetic field is exposed till the end of formation process of molecular coating.

EFFECT: improving reliability, corrosion resistance and service life of products from metals and alloys.
