Study on Electrolyte Dissolution Characteristics of GH4169 Super Alloy

Abstract GH4169 super alloy has a wide application in the field of aeronautics and astronautics, order to realize high quality fast processing complex workpieces with electrochemical machining (ECM), we have studied dissolution characteristics composite electrolyte, explored rule influence on voltage, feed speed, electrolyte pressure for gap (SG), material removal rate (MRR) surface roughness (Ra). The results showed that under 10%NaCl+16%NaNO3+4%NaClO3, 17.5V voltage 0.8MPa; temperature 30°C, 1.0mm/min cathode achieved efficiency machining, reached 0.8μm.
