Abstract

The invention provides a Ni-P chemical plating solution and a method for preparing a Ni-P nano-cubic boron nitride composite coating. Conventional Ni‑P electroless plating baths use potassium iodide as a single stabilizer, and its stability is limited in some cases. The present invention increases the stability of the Ni-P electroless plating solution through the potassium iodide / tin methanesulfonate composite stabilizer, and reduces the adverse effects of fine particles (such as nanoparticles) on the stability of the plating solution during the electroless plating process. The Ni-P nano-cubic boron nitride composite coating was prepared by using the above-mentioned Ni-P electroless plating solution. The composite coating prepared by the method is dense and uniform, has good bonding force, high hardness and wear resistance, and has excellent corrosion resistance, prolonging the service life of workpieces.
