Purpose of the development: Increasing the corrosion resistance and improving the mechanical properties of the surface of metal products, as well as providing the catalytic properties of the anode surface in the reactions of oxidation of organic substances.

Recommended application field: Machine building, automotive shipbuilding industries and alternative energy.

Technical characteristic: The coating, containing 50-80% of nickel has a microhardness of 410-680 HV, plastic, well adherent to electronegative and corrosion-unstable substrates, such as the surface of neodymium magnets. The multicharge coating consisting of layers of a nickel-copper alloy and a mixture of metals and their hydroxides has a catalytic activity increased by 1.5-2 times in electrooxidation reactions and the stability of surface properties, in comparison with a single-layer coating.

Advantages over analogues: In comparison with the world analogs, it is possible to obtain thicker compact multishape coatings in industrial conditions, thanks to the use of a poly-ligand electrolyte in combination with the proposed electrolysis regime and surface conditioning conditions.

The development stage readiness: tested in laboratory condition

Technical and economic effect: Economic feasibility of the use of multi-purpose coatings is due to the saving of materials due to an increase in the life of the products and a reduction in the costs of their production.

Description of the development:
()
Multilayer coatings consist of layers of various copper-nickel alloys up to 100 nm thick each. All layers of coating, which periodically alternate, are electrochemically deposited from one galvanic bath. This is a modern type of coating, which has not yet entered the practice of electroplating.
