Abstract

The invention discloses a nickel-iron-phosphorus / nano V8C7 composite electroplating solution. According to a formula, the composite electroplating solution comprises 70-120g / L of nickel sulfate, 10-20g / L of nickel chloride, 40-80g / L of iron sulfate, 10-20g / L of iron chloride, 20-40g / L of sodium hypophosphite, 10-25g / L of boric acid, 0.1-0.5g / L of a complexing agent, 0.1-0.5g / L of a brightener, 2-5g / L of a stabilizer and 5-20g / L of nano V8C7. Compared with the prior art, the composite electroplating solution disclosed by the invention has the advantages that a composite coating with nickel-iron-phosphorus amorphous alloy as a matrix and nano V8C7 as a second phase can be prepared, and the composite coating is free of microcracks on the surface and high in wear and corrosion resistance. The composite electroplating solution is simple in component; environmental hazards of all reagents are low; the process is stable and simple in operation; and the current efficiency is high.

Description

technical field [0001] The invention relates to a composite electroplating solution in the field of material surface treatment, specifically a nickel-iron-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 character...
