In order to explore the effect of weld area and groove structure on the damage effect of laser irradiation on titanium alloy and ceramic coating, the experiment of continuous laser irradiation on welding seam and groove area of titanium alloy was studied, while the surfaces of the specimens were coated with or without anti-laser ceramic material. The following conclusions were obtained: the ceramic coating can protect the titanium alloy substrate from the damage of high power laser effectively; the laser resistance of ceramic coating on the welding seam area is weakened, but it still protects the titanium alloy effectively; the damage of laser on the edge and the corner structure of titanium alloy with groove structure is aggravated with the increasing of laser power density, and under the same laser density, the damage inside the groove is less than that outside, while that of corner is less than edge. Micromorphology results show that the ceramic coating undergoes a series of physical and chemical changes and phase transformation to absorb a large amount of thermal energy converted from luminous energy, which has a protective effect on the titanium alloy.
