Abstract

Abstract: This study introduces the concept of compositionally-graded electrochemical additive manufacturing of advanced metal alloys. The feasibility was demonstrated using a NiCoFeCu system for electromagnetic applications. The effects of grading frequency and voltage on output geometry and elemental composition were studied. Application of constant signals throughout pillar build yielded varying width and elemental composition along the pillar length. Additional grading of voltage from low to high favoured wider pillars and enhanced copper content. Auxiliary plating effects were used to explain compositional deviations from conventional electroplating. Frequency response varied with voltage, suggesting its use as a secondary, fine-tuned parameter.
