The technology of metallization of duralumin alloy D16 and cast aluminum alloy AL4 with method of electrodeposition by rubbing has been developed, which allows excluding operations of chemical etching and clarification without reducing the adhesion of coatings. In these operations, such high-concentration acids as nitric, sulfuric, hydrofluoric and others can be used. Instead, it is proposed to use cathode-anode processing operations and application of the zinc-nickel-boron nitride alloy in a universal, much more environmentally friendly electrolyte for simultaneous etching and deposition of coatings. A technology for applying a gradient zinc-nickel-boron nitride alloy with electrodeposition by rubbing has been developed. The process of copper plating of aluminum alloys from pyrophosphate electrolytes with electrodeposition by rubbing is studied. Such modes of coating as copper and zinc-nickel-boron nitride ones using anode tools with an area of 1 cm 2 and 3.75 cm 2 were established.
