Abstract

The invention discloses a multi-layer nickel electroplating additive for improving stability. The multi-layer nickel electroplating additive is prepared from raw materials of 2-15 mL / L of a cylinder opening agent, 1-10 mL / L of a microporous nickel additive and 1-2 mL / L of a wetting agent according to the concentration in a plating solution. The invention further discloses a nickel plating processcontaining the multi-layer nickel electroplating additive. The multi-layer nickel electroplating additive is added into the electroplating solution at the addition volume of 1-1.4 mL / L, and during nickel plating, the temperature of the plating solution is 50-60 DEG C, the current density is 16-19 mA / cm<2>, and the electroplating time is 18-25 min.

Description

technical field

[0001] The invention relates to the field of electroplating industry, in particular to a multilayer nickel electroplating additive with improved stability. Background technique

[0002] The electroplating process is a method of plating a layer of metal on a conductor using the principle of electrolysis. During electroplating, the plated metal or other insoluble materials are used as the anode, and the workpiece to be plated is used as the cathode. The cations of the plated metal are reduced to a coating on the surface of the cathode. Electroplating can improve the corrosion resistance, strength, hardness, wear resistance, electrical conductivity, heat resistance and other properties of the cathode, and can also beautify the surface decoratively. The multi-layer electroplating process is the electroplating process of several layers of different materials on the same electroplating processed product. Studies have shown that multi-layer electroplating can not on...
