Abstract

The invention belongs to the field of electrochemical process technology and relates to a selective metal electro-deposition device and application thereof. The metal electro-deposition device is characterized by comprising a liquid storage tank for containing electrolyte, a power supply namely an ultrasonic power supply electrically connected with a cathode and an anode correspondingly in electro-deposition process, an ultrasonic assistant jet apparatus supported by a rack and a three-dimensional numerical control platform which comprises a motion actuator, the rack and a computer, wherein the liquid storage tank is also externally provided with a peristaltic pump for supplying jet pressure for the electrolyte and a control valve for controlling the flow of the electrolyte, the liquid storage tank is internally provided with a temperature controller for keeping the temperature of the electrolyte, and an electrolyte nozzle is arranged at the bottom of the ultrasonic assistant jet apparatus. 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...
