Electrical discharge machining of nickel-based super alloy

摘要：

　　This paper presents an experimental investigation of the machining characteristics of IN718 nickel-based super alloy in wire electrical discharge machining (WEDM) process.During experiments,parameters of discharge current and pulse on time were changed to explore the effect on various aspects of the surface characteristic.Scanning electron microscopy (SEM),surface roughness and micro hardness tests were performed.Experimental results reveal that the surface roughness will increase with the increasing of current and pulse duration.Micro hardness tests show there is no hard phenomenon.
