Three-dimensional surface shot peening jet electrodeposition manufacturing method and device

Abstract

The invention provides a three-dimensional surface shot peening jet electrodeposition manufacturing method and device. According to the manufacturing method and device, a deposition solution and hard particles are mixed and deposit on a conductive substrate in a spraying manner, so that the rapid manufacturing technology of electrodeposition is realized, the growth rate of grains in the electrodeposition process is slowed down, the purpose of refining the grains is reached, and the quality of a deposition layer is dramatically improved; with combination of the shot peening strengthening technology and the electrodeposition technology, the defects of loose texture, pockmarks, pits and the like of the deposition layer caused by single electrodeposited cathode hydrogen evolution and impurity adhesion can be effectively overcome, and the hardness and the compactness of the deposition layer are improved; meanwhile, by introducing a five-axis linkage numerical control machining system, processing formation of a three-dimensional space can be realized, and the uniformity and the shape accuracy of the deposition layer are improved; and the technology can be widely applied to production of noble metal devices and parts in complex shapes and can also be used for surface rapid coat-plating, a strengthening technology and the like.

Description

technical field [0001] The invention relates to the field of rapid prototyping in manufacturing technology, in particular to a three-dimensional surface shot peening jet flow electrodeposition manufacturing method and device. Background technique [0002] As a new processing and forming method, electrodeposition technology has been widely developed and applied in the field of micro-manufacturing technology and surface treatment technology due to its good controllability of process parameters, such as micro-motors, micro-sensors, micro-parts Good results have been achieved in forming and repairing, parts surface coating and corrosion resistance. Therefore, electrodeposition technology is one of the most attractive research fields in the 21st century. [0003] Due to the many deficiencies in the deposition rate, the regioselectivity of deposition, the bonding strength between the deposited layer and the substrate, and the grain size, physical properties and surface morphology...

AI Technical Summary

Problems solved by technology

[0004] Among the deposition methods realized by the existing electrodeposition technology, the method is simple but the effect is not obvious, or the effect is good but the device is complex and operable, which greatly limits the wide application of electrodeposition technology.

And the surface of the deposited layer will deteriorate the deposition quality with the prolongation of the deposition time, thereby affecting the density and uniformity of the material
