Abstract
A method of strengthening through real-time coupling of electrical pulses and laser shock waves is provided. The initial time and duration of the electrical pulses are controlled to be matched with the initial time and duration of the laser shock waves, so that the electrical pulses and the laser shock waves are coupled in real time for material strengthening, the plasticity and the strength of the material are greatly improved, and a large area of the workpiece is uniformly strengthened. By simultaneously introducing the electrical pulses into the pulse current-assisted LSP, a great strengthening effect is achieved through the combination of the electrical pulses and the pulse current-assisted LSP in a short time, thereby reducing the internal defects of the material to a certain extent and further increasing the fatigue life of the material.
