Abstract

The invention discloses a nickel-phosphorus / nano V8C7 composite plating liquid. The plating liquid comprises the following components: 120-180 g / L of nickel sulfate, 10-30 g / L of nickel chloride, 30-50 g / L of sodium hypophosphite, 10-25 g / L of boric acid, 0.2-2 g / L of a complexing agent, 0.1-0.5 g / L of a brightening agent and 5-20 g / L of nano V8C7. Compared with the prior art, by adopting the composite plating liquid disclosed by the invention, a composite plate taking nickel-phosphorus amorphous alloy as a basal body and the nano V8C7 as a second phase can be prepared, and the surface is free of microcracks. The nickel-phosphorus / nano V8C7 composite plating liquid is high in abrasion resistance and corrosion resistance. The composite plating liquid is simple in composition, little in damage of reagents to the environment, stable in technology, simple in operation and high in current efficiency.

Description

technical field [0001] The invention relates to a composite electroplating solution in the field of material surface treatment, specifically a nickel-phosphorus / nanometer V 8 C 7 Composite plating solution. Background technique [0002] Composite electroplating uses electrochemical methods to co-deposit metals (or alloys) and solid particles (or fibers). There is almost no diffusion phenomenon between the base metal and the added solid particles in the composite coating, so it has the comprehensive properties of the base metal and solid particles. The particularity of amorphous structure (short-range order) makes amorphous materials have excellent mechanical properties, corrosion resistance, and chemical activity compared with traditional metals. However, when the amorphous material is deformed at room temperature, it is easy to induce the local adiabatic shear band to form a single shear crack and suddenly break and fail. On the other hand, the structural characteristic...
