How to remove chemical nickel layer on aluminum alloy

2018-12-02

The more common chemical method is soaking in nitric acid with a volume fraction of 50%. This method should pay attention to the enhanced monitoring of surface corrosion during later use.

It has been reported that the following electrolysis removal methods are used: in a solution containing sulfuric acid (density = 1.84 g/cm3) 1070 to 1200 g/L, glycerol 8 to 10 g/L, the anode current density is 5 to 10 A/dm2, and the voltage is 12 V. The cathode uses a lead plate and it is removed at room temperature.
