Abstract

The invention discloses a nano semibright nickel plating solution, which belongs to technical field of surface treatment, and the ingredient of the solution comprises: 250-300 g / L of nickel sulfate, 35-50 g / L of nickel chloride, 40-50 g / L of boric acid, 1*10-3-5*10-3g / L of rare earth oxide, wherein the rare earth oxide is lanthanum oxide and / or yttrium oxide, compared with the existing semibright nickel plating solution, the invention is better on the plating solution dispersibility, can cause the plating layer to be bright and have fine crystallization, is small on pore number unit area, and can improve multiplayer nickel corrosivity.

Description

technical field [0001] The invention relates to an electroplating solution, in particular to a nano semi-bright nickel electroplating solution. Background technique [0002] Semi-bright nickel is a commonly used intermediate layer in electroplating. In addition to achieving leveling, uniformity and flexibility, the coating must be as bright as possible, and the semi-bright nickel coating must have good compactness and fewer pores. Conducive to the corrosion resistance of multilayer nickel. In modern electroplating production, semi-bright nickel nickel plating occupies an important position as bright nickel nickel plating. The main purpose of semi-bright nickel is not decoration, but to improve the corrosion resistance of multi-layer nickel. The multi-layer nickel system composed of semi-bright nickel / high-sulfur nickel / bright nickel is anode sacrificial type. One of the important factors affecting the corrosion resistance of this system is bright nickel and semi-bright nic...
