Abstract

The invention relates to a manufacturing methd and device for fibre laser and electrochemical complex nanosecond pulse deposition. According to the invention, a fibre laser technology is introduced to an electrochemical deposition manufacturing system to effectively increase the flexibility of the optical beam transmission and is combined with a numerical control machining system to realize a processing requirement of a complex three-dimensional space structure. In the machining process, a laser beam with nanosecond pulse is coupled with electrochemical nanosecond pulse current, the nanosecond electrochemical pulse deposition process can avoid the concentration polarization on the surface of the electrode and reinforce the regioselectivity of the deposition reaction, at the same time, the pulsation effect of the laser can effectively eliminate the hydrogen bubbles in the electro-deposition process so that the localization effect of the electrochemical deposition and the compactness of the material can be obviously increased and the microcomponent deposition formation of the high performance metal material can be realized. The manufacturing method and device provided by the invention is suitable for manufacturing three-dimensional micro devices made of high performance metal materials, belonging to the field of microfine rapid shaping process.
