Research on Electrolyte Plasma Polishing Process for Additive Manufactured Inconel 718
To address the issue of nickel-based superalloy components manufactured by additive manufacturing failing to meet the surface quality requirements of aerospace applications,the paper conducted experiments on additive manufactured Inconel 718 samples by electrolyte plasma polishing technology.Based on fractional factorial and response surface analysis,the influence of voltage,electrolyte temperature,processing time,polishing agent and complexing agent concentration on the surface quality and material removal rate were studied.Simultaneously,an optimization of the processing parameter combinations was performed.The result indicated that when using polishing voltage of 314.4 V,electrolyte temperature of 70℃,processing time of 15 min,polishing agent concentration of 2%,complexing agent concentration of 2.5%,the surface roughness of the additive manufactured Inconel 718 component can be reduced from Ra2.93 μm to Ra0.307 μm,with a material removal rate of 2.072 μm/min.
