A phosphoric acid-nickel chloride reaction system was designed by utilizing the comprehensive corrosion properties of phosphoric acid and the activation effect of chloride ions. By characterizing surface potential and microscopic morphology, the nickel immersion process was analyzed at different phosphoric acid concentration and temperature. The result shows that the concentration of phosphoric acid is a key factor affecting the surface potential and morphology of the nickel-immersed coating. When the concentration of phosphoric acid is 25% and the temperature is 30℃, nickel-immersed coating with stable chemical properties, good coating and uniform grain size can be prepared. In this reaction system, the nickel-immersed coating grows in a spherical manner after nucleation. After reacting for 600 s, a nickel-immersed coating with a thickness of about 1 μm is obtained, and its surface potential can reach about -0.51 V.
