Abstract :
The effect of processing parameters on the topography, microstructure and chemical composition in electrical discharge alloying has been studied. This paper details the high-energy micro-arc alloying of In718 superalloy during electrical discharge surface alloying using deionizer water with NiCrAl electrode. Scan electron microscope (SEM), energy dispersive spectrograph (EDS) were performed. The results suggest that the surface is saturated with oxygen, aluminum and Cr. The value of the spot diameter is increase with increasing output processing power.
