| titleOfInvention | A kind of preparation method, product and application of composite membrane with self-healing function |
| abstract | The invention discloses a preparation method, product and application of a composite film with self-healing function, and relates to the technical field of surface treatment of metal materials. The method includes the following steps: adding cobalt salt, tungsten salt, complexing agent and buffering agent into water to obtain a mixed solution, adjusting the pH value to be acidic to obtain an acidic solution; adding cerium oxide and a surfactant to the acidic solution to obtain an electrolytic solution liquid system; the metal substrate is placed in the electrolyte system for electrodeposition to obtain a composite membrane with self-healing function. In the present invention, by performing constant potential composite electrodeposition on the metal material substrate, a micron-level composite film with self-repairing function and a thickness of 6-8 μm is finally formed on the surface of the metal material. The composite film is continuous and complete, has a dense structure, and has a hardness of 251.0HV, when cracks occurred on the surface, it was placed in a 3.5wt.% NaCl solution for 7 days, that is, in the presence of the corrosive medium Cl- , the cracks healed. |
