METHOD FOR COATING RECEIVING Russian patent published in 2008 - IPC C25D11/08 

FIELD: metallurgy, plating.

SUBSTANCE: invention concerns galvanostegy field. Particularly it concerns micro-arc oxidation and can be used in mechanical engineering and instrument engineering. During the oxidation process on the surface of oxidised detail under pressure through jets contacting to cathode it is fed oxygen, and oxidised surface contacting to anode at that relative to jets executes forward and rotary movements, providing uniform distribution of oxygen on oxidised surface.

EFFECT: thickness value uniformity, hardness, breakdown tension of coatings, formed by oxidation on products made of aluminum alloys of irregular shape and simultaneous increasing of processing capacity.
