Electronickelling solution formula used for improving uniform distribution performance of neodymium-iron-boron manget coating and electronickelling method

The invention discloses an electronickelling solution formula used for improving the uniform distribution performance of a neodymium-iron-boron magnet coating and an electronickelling method. The formula comprises the following components according to the concentration: 70-150 g/L of nickel chloride, 80-300 g/L of potassium chloride or sodium sulfate conducting salt, 35-55 g/L of boric acid, and 0.1-0.9 mg/L of benzoic sulfimide, wherein the PH value is 4.0-4.8. The electronickelling solution formula adopts high-concentration nickel chloride to replace common nickel sulfate in the prior art, so that the cathode polarization degree is improved, and the plating solution dispersive capacity and electrical conductivity of nickel chloride are superior to those of nickel sulfate; high-concentration potassium chloride/sodium sulfate conducting salt is adopted, so that the conductivity of the plating solution is greatly improved; and complexes adopted in a traditional formula process are removed, the medical liquid r
