SOLUTION USED FOR CHEMICAL DEPOSITION OF COMPOSITE NICKEL COATINGS Russian patent published in 2012 - IPC C23C18/36 B82B1/00

Abstract RU 2465374 C1

FIELD: metallurgy.

SUBSTANCE: solution used for chemical deposition of composite nickel coatings contains nickel sulphate, sodium acetate, sodium hypophosphite, inert particles, which include nanodisperse particles of aluminium oxide and have the size of 50 - 80 nm, at the following content, g/l: nickel sulphate 20, sodium acetate 10, sodium hypophosphite 10, nanodisperse particles of aluminium oxide 0.3.

EFFECT: invention allows increasing the quantity of particles included in nickel coating of particles, increasing their uniform distribution in the coating, as well as improving micro hardness and corrosion resistance of the obtained nickel coating.
