Abstract As a new surface treatment technology, electrospark deposition (ESD) has the advantages of small heat input, small thermal impact and deformation on the substrate, good bonding strength between the coating and the substrate. And the deposition coating do not easy to peel off, which has been widely applied in aerospace, military and other industries to strengthen the surface of parts, as well as repair the surface of failed parts. The principle and characteristics of ESD technology were introduced. The domestic and foreign development of ESD technology in recent years was summarized. The application of ESD technology in the field of aeronautical manufacturing was analyzed. By considering the existing problem of the current ESD deposition technologies, suggestions on accelerating its research and development were proposed.
