Description

technical field

[0001] The invention relates to a graphene oxide nickel-phosphorus composite plating solution, a preparation method thereof and the use of the graphene oxide nickel-phosphorus composite plating solution to form a graphene oxide nickel-phosphorus composite coating by electroless plating on the surface of a steel alloy. technical background

[0002] Electroless plating is a metal deposition process in which metal ions are reduced under the self-catalysis of the metal surface by an appropriate reducing agent in the solution. Electroless plating can enhance the corrosion resistance and wear resistance of materials, and is the most economical technical means to prolong the service life of materials. With the development of science and technology, the single electroless nickel plating is increasingly unable to meet the requirements of industrial development. Therefore, chemical composite plating with good performance is developed. Composite plating is a surface t...
