Abstract

The invention belongs to the technical field of electroplating, and particularly relates to an alkaline graphene zinc-iron alloy electroplating solution and an electroplating process thereof. The alkaline graphene zinc-iron alloy electroplating solution of each liter is prepared from 8-13 g of zinc oxide, 90-125 g of sodium hydroxide, 50 g of seignette salt; 50-90g of graphene nano-particles, 0.35-0.6 g of Fe+, 4 ml-8 ml of a DE additive, 0.03 g-0.06 g of vanillic aldehyde and the balance water. The method comprises the steps of S1, impurity removal and degreasing, S2, water washing acidification; S3, metal electroplating and S4, water washing drying. The temperature of the electroplating solution ranges from 15 DEG C to 30 DEG C; the pH of the electroplating solution ranges from 9 to 14;seignette salt serves as a complexing agent and is most complex, and meanwhile seignette salt is the impurity shelter of alkaline zincate zinc plating; and meanwhile, a certain amount of free tartaricacid exists in the electroplating solution, and the phenomenon that the electroplating solution is instable during electroplating can be avoided.

Description

technical field [0001] The invention belongs to the technical field of electroplating, in particular to an alkaline graphene-zinc-iron alloy electroplating solution and an electroplating process thereof. Background technique [0002] In the field of surface technology, with the development of the times, the protection performance requirements of many products are more stringent, and single-metal plating can no longer meet the requirements, and the performance of alloy plating is better than that of single-metal plating. Since the zinc coating is a good protective layer for the steel substrate, the alloy coating in the field of protective electroplating is still based on zinc. For example, zinc-iron alloy electroplating, zinc-nickel alloy electroplating and zinc-cobalt alloy electroplating and other technologies are more and more widely used due to their excellent corrosion resistance. [0003] Among them, the properties of zinc-iron alloy plating solution, namely current ef...
