Embodiment 1

[0022] Example 1: Effect of pH on coating composition and current efficiency.

[0023] The composition of the electroplating solution is as follows:

[0024] Zinc sulfate 0.08mol / L, nickel sulfamate 0.1mol / L, sodium hydroxide 0.03mol / L, ammonium chloride 0.02mol / L, boric acid 0.0025mol / L, β-naphthoic acid sodium 0.002mol / L, leucine Acid 0.0001mol / L, isoleucine 0.0001mol / L, brightener, complexing agent, pH8.8~9.2, solvent is water.

[0025] Plating method:

[0026] Put the cleaned copper piece into the palladium ferry, the current density is 0.1-0.3A / dm2, the temperature of the bath is 28°C, and the tank pressure is 4V.

[0027] Electroplating effect: It can be seen from Table 1 that the electroplating effect is between pH 8.2 and 9.2.

Abstract

The invention discloses zinc-nickel alloy plating liquid. The zinc-nickel alloy plating liquid comprises 0.08-0.1mol / L of zinc sulfate, 0.1-0.2mol / L of nickel sulfamate, 0.01-0.05mol / L of sodium hydroxide, 0.01-0.03mol / L of ammonia chloride, 0.002-0.003mol / L of boric acid, 0.001-0.002mol / L of beta-sodium naphthenate, 0.0001-0.0002mol / L of leucine, 0.0001-0.0003mol / L of isoleucine, brightener and complexing agent, wherein pH is 8.8-9.2, and a solvent is water. The zinc-nickel alloy plating liquid has the advantages that an electroplating matrix using the plating liquid is good in corrosion resistance, and a plated layer is compact, even, and small in particle.

Description

technical field [0001] The invention belongs to the technical field of metal plating solution, and in particular relates to a zinc-nickel alloy plating solution and its application. Background technique [0002] Among the zinc alloys, the zinc-nickel alloy coating is an excellent protective coating. The corrosion resistance of the zinc-nickel alloy containing 7% to 9% of nickel is more than three times that of the zinc coating, and the zinc-nickel alloy containing about 13% of nickel It is more than 5 times that of zinc coating, and has the best corrosion resistance, especially after heating at 200-250 °C, the passivation film can still maintain good corrosion resistance. [0003] The zinc-nickel alloy ferry solution is mainly divided into two types: one is the weak acid system, pH=4~5, and the mixed type of ammonium chloride and potassium chloride is mostly used. This kind of ferry solution has simple components and high current efficiency. The top of the liquid is easy to...
