Description	Journal: Journal of Physics: Conference Series This paper presents a new method for electrolyte-assisted UV laser processing of thermal barrier coating materials. Under a certain thickness of the electrolyte layer, the ultraviolet laser beam is focused on the surface of the workpiece, the laser galvanometer realizes the rapid rotation of the thermal barrier coating material by the ultraviolet laser beam, and the "two-photon absorption" removes the matrix of the thermal barrier coating material, and collapses. The cavitation bubble action avoids the secondary adhesion of the processed material, meets the processing precision requirement (±0.05mm), and realizes the cold processing of the non-recast layer of the thermal barrier coating micropores. The improved ant colony algorithm is used. The minimum diameter difference is the objective function, the upper and lower diameter difference and the upper and lower machining precision are the constraints. The thermal barrier coating processing optimization model is established, and the process parameters are optimized and experimentally verified.
