| titleOfInvention | A kind of preparation method of electrodeposited cobalt-based composite coating |
| abstract | A preparation method of an electrodeposited cobalt-based composite coating layer belongs to the technical field of surface protection. The method includes the following steps: (1) preparing a composite plating solution, which is prepared from cobalt sulfate, cobalt chloride, boric acid, phosphoric acid, surfactant and water. (2) Add the pretreated ceramic powder to the composite plating solution and stir to make the powder evenly dispersed in the plating solution. (3) Composite electrodeposition is carried out by using pulse current and two-electrode parallel device, the cleaned cobalt plate is used as the anode, the workpiece to be plated is the cathode, and a cobalt-based composite coating is formed on the surface of the workpiece to be plated. (4) The workpiece on which the cobalt-based composite coating is formed is heat-treated. The invention adopts technical means such as using pulse power supply to replace DC power supply, adjusting current density, heat treatment of coating layer, chemical pretreatment of powder particles, etc., so as to significantly improve the bonding strength of powder particles and metal matrix, improve the uniformity of the coating layer, and reduce the roughness of the coating layer. degree, and enhance the coating performance. |
