CHEMICAL NICKEL PLATING PLANT Russian patent published in 2024 - IPC C23C18/32 

FIELD: chemical nickel plating.

SUBSTANCE: invention can be used in application of nickel-phosphorus coating by chemical method on small parts, as well as overall structural parts of complex profile. Apparatus has a tank for heating working solution 1, filled with heat carrier 2, in which there is coil 3 and electric heaters 4. Coil is made of a metal alloy which is inert to the working solution. Delivery branch of pump 5 is connected by pipeline 6 to coil 3, and the suction branch is connected by pipeline 7 to the chemical nickel plating bath 8. Installation is equipped with two containers, one of which is for correction solution 9, and the other is for pH stabilization solution 10, connected to pipeline 13 connecting coil 3 with chemical nickel plating bath 8. Control unit 14 is electrically connected to electric heaters 4 and pump 5.

EFFECT: ensuring stability of the chemical nickel plating process owing to uniform distribution of the working solution of a certain concentration and temperature in the entire volume, enlarging technological capabilities of the apparatus.
