FIELD: chemistry.
SUBSTANCE: method involves mounting a bath onto the article to undergo processing on the area to be coated, mounting an anode with a membrane for separating gases, connecting the bath to air-ducts, main pipelines for supplying and outlet of solutions, sealing the joint between the bath and the surface of the processed article, heating the article with a degreasing solution, washing, activating the surface and applying an electrolytic or chemical coating. All processes are carried out while constantly circulating the solutions in the inter-electrode space.
EFFECT: unification and reduction of the cost of local plating, increase in hardness and uniformity of the coating.
