Abstract

The invention provides a nickel pretreatment method for improving the appearance of a nickel layer of a stainless steel / copper-nickel-zinc alloy material. The method comprises the steps of liquid medicine preparation, equipment inspection, electroplating treatment and cleaning treatment, wherein the step of liquid medicine preparation comprises the steps of dissolving nickel chloride in deionized water, then adding a hydrochloric acid solution, uniformly mixing, then adding a special additive for 3-5 times, uniformly mixing, and fixing the volume for later use. According to the nickel pretreatment method for improving the appearance of the nickel layer of the stainless steel and the copper-nickel-zinc alloy material, the problem that a product containing the stainless steel and the copper-nickel-zinc alloy material at the same time is poor in appearance after nickel plating is solved, the idea is expanded for product design and material selection, more molds do not need to be used, the assembling procedures are effectively reduced, the whole product cost is reduced, and the appearance defects of floating and white spots after nickel plating on the surfaces of the copper-nickel-zinc alloy material and the stainless steel in the prior art are overcome. The method provided by the invention is simple and easy to implement, green and environment-friendly, and is an environment-friendly process.

Description

technical field [0001] The application relates to a nickel pretreatment method for improving the appearance of a nickel layer of a stainless steel / nickel nickel material, which belongs to the field of connector electroplating. Background technique [0002] In the prior art, the product has stainless steel and nickel-nickel metal materials at the same time. Since the stainless steel and nickel-nickel metal materials contain different alloy components, appearance defects such as blooming and white spots will appear after nickel-plating on the surface of the nickel-nickel metal material and stainless steel. Therefore, how to provide a new surface nickel pretreatment process, so that the surface after nickel plating is smooth and bright, and the color and luster is uniform, is an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a nickel pretreatment method for improving the appearance of the nickel layer of stain...
