The selective metal electro-deposition device can improve the hardness, compactness and electro-deposition speed of a settled layer in the existing electro-deposition technology, lower the residual stress of a clad layer, and realize the selectivity of an electro-deposition area and the electro-deposition forming of parts of simple shape.

Description

technical field [0001] The invention belongs to the technical field of electrochemical processing, and is specifically designed as a selective ultrasonic-assisted spraying metal electrodeposition device. Background technique [0002] Metal electrodeposition refers to the process of reducing metal ions in the electrolyte under the action of direct current and depositing them on the surface of parts to form a metal coating with certain properties. [0003] Spray electrodeposition is a new electroplating process developed in recent years. It is a local high-speed electrodeposition technology aimed at improving the performance and forming accuracy of the forming layer. Rapid forming of spray electrodeposition has high replication accuracy and repeatability, and fast deposition rate. And the performance of the deposited layer is excellent. Partial plating can be applied to large parts, and it can be used for repairing worn or damaged parts and plating in blind holes and deep hol...

AI Technical Summary

Problems solved by technology

[0005] The existing spray electrodeposition technology still has problems such as low degree of automation of processing parts, low utilization rate of electrolyte, uneven thickness of deposited layer, slow electrodeposition speed and poor material properties.

These problems lead to the fact that spray electrodeposition and ultrasonic-assisted spray electrodeposition technology do not improve the surface quality and performance of materials in the actual application process, and the processing quality is not easy to control, and even make parts scrapped, which seriously restricts the development of technology and in actual production. application, so so far, most of the research is in the laboratory stage, far from industrialization
