The electrolysis effects of Ni-based alloys in different electrolytes were investigated.Three kinds of Ni-based alloys

including N6

Cr20 Ni80 and 4 J43

were analyzed by electrolysis in single oxysalt electrolyte and mixed oxysalt electrolyte

respectively.Non-metallic inclusions in the alloys were separated and observed by scanning electron microscope.Meanwhile

anode polarization curves of N6

Cr20 Ni80 and 4 J43 in different electrolytes were obtained by electrochemical workstation.Morphology of inclusions separated was observed by SEM（scanning electron microscopy）.The results reveal that nonmetallic inclusions are separated smoothly from Ni-based alloys in mixed oxysalt electrolyte

and the pH value keeps at approximately 5 during electrolysis process

presenting the satisfied transpassivity.SEM analysis shows morphology change absence of non-metallic inclusions separated.The mixed oxysalt electrolyte can improve the precision of non-metallic inclusions separation from Ni-based alloys.
