With the wide application of superalloys with thermal barrier coatings,the process of femtosecond laser hole making has also faced higher challenges.In this paper,by studying the interaction principle of femtosecond laser and zirconia ceramics,the current when the energy of a single pulse is about 80 μJ,the material in the focal point can be completely removed,which is verified by experiments.Through a large number of optimization experiments,a segmented hole making method for coated superalloys is proposed,and the optimal process parameters are summarized,which can be used to make holes at any angle.The surface quality of the obtained microporous coating is intact and the transition section cracks and has no hole wall quality is good.
