Investigation of mechanical, microstructural and corrosive properties of ERNiCrMo-3 – ERCuSiA based additively manufactured functionally graded material
The exploration involved harnessing the Wire Arc Additive Manufacturing (WAAM) technique in conjunction with Gas Tungsten Arc Welding (GTAW) procedures. This combination created functionally gradient materials. These functionally graded materials were shaped using ERNiCrMo-3 and ERCuSiA alloys. Comprehensive analyses included microstructural composition, mechanical properties, and corrosion susceptibility of the produced component. Infusion of copper expanded the constitutional supercooling zone. Copper’s exceptional growth restriction factor caused columnar and dendritic forms in the ERNiCrMo-3 - ERCuSiA FGM to change. The ERNiCrMo-3 - ERCuSiA FGM’s tensile strength, microhardness, and density exceeded their component materials. Interestingly, FGM mechanical properties improved with copper concentration. During electrochemical corrosion investigations, a remarkable observation occurred. FGMs with higher copper concentration were less resistant to corrosion than those with lower copper content. The extensive analysis found that the ERNiCrMo-3 - ERCuSiA FGM can improve mechanical performance. Paradoxically, this improvement reduces the alloy’s corrosion resistance. Quantitative tests showed 120%, 120%, and 60% increases in microhardness, tensile strength, and yield strength. A comparison of copper-based electrode substrates with FGMs confirmed these findings. A 10% drop in elongation and density results from the shift between copper-based electrode substrates and FGMs.
