A technique of electro stream machining used to process the film cooling holes of single crystal turbine blade of aero-engine is described. The mechanism of electro stream machining
the effect of technology on the microstructure of single crystal matrix
the characteristics of orifice morphology and the control method are described in detail. In particular
an effective process control method is proposed for several typical orifice defects to ensure the surface quality of film cooling holes and obtain good orifice morphology
