Abstract: Electrodeposition is the most widely used method for preparing nickel-based composite coatings at present. The characteristics of different electrodeposition methods are introduced. The effects of current density, bath pH, surfactant, content and size of second phase particles on the quality of nickel-based composite coatings are reviewed. The types and application status of nickel-based composite coatings are summarized. In the end, the future development of electrodeposited nickel-based composite coatings is prospected.
