Embodiment 1

[0065] The pure aluminum surface treatment of embodiment 1 nickel sulfamate electroplating solution

[0066] Liquid nickel sulfamate 650g / L, boric acid 30g / L and nickel chloride 25g / L are continuously electroplated on aluminum coil samples according to the short-process continuous nickel plating process on aluminum coils, and the process in turn is: degreasing→water washing → degreasing → water washing → pickling → water washing → zinc dipping → water washing → pickling → water washing → zinc dipping → water washing → pickling → water washing → zinc dipping → water washing → electroplating nickel → water washing → deionized water washing → drying → drying.

[0067] Among them, degreasing is 60°C, 25 seconds; pickling is 25°C, 15 seconds; zinc dipping is 25°C, 15 seconds; electroplating nickel process uses 8.5A / dm 2 Current density, the distance between cathode and anode is 5 cm, 60°C, 90 seconds. After the sample is washed with water, washed with pure water and dried, a dense...

Embodiment 2

[0069] The pure aluminum surface treatment of embodiment 2 nickel sulfamate electroplating solution

[0070] Liquid nickel sulfamate 650g / L, boric acid 30g / L, nickel chloride 25g / L, 602 brightener 6ml / L, carry out continuous electroplating nickel treatment on aluminum coil samples according to the process of continuous nickel plating of aluminum coil short process, the process The sequential process is: degreasing → water washing → degreasing → water washing → pickling → water washing → zinc dipping → water washing → pickling → water washing → zinc dipping → water washing → pickling → water washing → zinc dipping → water washing → electroplating nickel → water washing → deionized water washing → Blow dry → Dry.

[0071] Among them, degreasing is 60°C, 25 seconds; pickling is 25°C, 15 seconds; zinc dipping is 25°C, 15 seconds; electroplating nickel process uses 12A / dm 2 Current density, the distance between cathode and anode is 5 cm, 60°C, 90 seconds. After the sample is wash...

Abstract

The invention relates to a nickel sulfamate electroplating solution which comprises nickel sulfamate, boric acid and nickelous chloride. A formed nickel-plated layer which has favorable stability and is continuous and complete without pinholes, bubble shedding and residual stress is formed after a metal surface is plated by the electroplating solution. The smoothness and the brightness of the obtained plated layer are improved after a certain amount of brightener is added to the electroplating solution so that the metal surface is smoother and more attractive.

Description

technical field [0001] The invention relates to a metal surface electroplating solution, in particular to a nickel sulfamate electroplating solution and a nickel plating method. Background technique [0002] Electroplating technology is one of the important contents of surface engineering technology and an indispensable link in the manufacturing industry chain. Although the electroplating layer has the characteristics of functionality, anti-corrosion and decoration, the electroplating industry is a highly polluting industry, and its production process requires a lot of energy, water and non-ferrous metal consumption. With the rapid development of science and technology and the rapid development of advanced manufacturing industry, more and higher requirements are put forward for electroplating technology. For this reason, new electroplating processes, new materials and new equipment are constantly emerging. [0003] Nickel plating plays an important role in electroplating pr...
