Abstract

In this paper, CoCrAlY coating was prepared on the substrate, Ni-based super alloy (GH4169), using Air Plasma Spray (APS). After deposition, the coating was irradiated by High Current Pulse Electron Beam (HCPEB) with different number of pulse beam. Then the micro-structure of coating surface, like the morphology and roughness, were characterized by scanning electron microscope (SEM) and 3D optical microscope. When the coating treated with 20 times pulse beam, the roughness is 28.02 µm. Besides, the surface was remelted into a compact appearance with many bulged nodules connected.
