The invention relates to a surface treatment method and device for a workpiece coating. The method is characterized by comprising the following steps: performing spinning friction processing on a coating on the surface of a base material of the workpiece by adopting a spinning friction head of which the top is planar or arc-shaped; and applying ultrasonic vibration on the workpiece or the spinning friction head during spinning friction processing. The device mainly comprises a worktable for clamping and allowing a processing electrode to rotate, a spinning friction device integrated with an ultrasonic generator, and an ultrasonic power supply. According to the device, the spinning friction treatment and ultrasonic modification are integrated, the inherent coating defects (such as holes, discontinuous coatings and coating loosening) in an electrosparking deposition process are improved under the co-action of the ultrasonic waves and spinning friction, the coating material is kept pure and invariable, and the physical and mechanical performances are kept invariable. The device has the advantages that improving the coating performance is improved, operation is simple, cost is low, applicability is high and the like.
Description
technical field [0001] The invention relates to a spinning friction treatment method for workpiece coating, which is suitable for improving the material coating, especially the bonding strength between the coating and the substrate of the coating electrode, improving the compactness of the coating, and further improving the coating electrode. life requirements. Background technique [0002] With the development of the automobile industry, ordinary steel plates can no longer meet the needs of corrosion resistance and lightweight development of automobiles. In order to meet the development needs of the automobile industry in the future, various coated steel sheets, especially galvanized steel sheets, are more and more widely used in automobiles. At the same time, in order to save energy and reduce emissions, automobile lightweight has gradually become one of the main issues considered by the automobile production industry. Due to the needs of the development of lightweight a...
