3D PRINTED N-DOPED COCRFENI HIGH ENTROPY ALLOY WITH MORE THAN DOUBLED CORROSION RESISTANCE IN DILUTE SULPHURIC ACID

3D printed N-doped CoCrFeNi high entropy alloy with more than doubled corrosion resistance in dilute sulphuric acid

Abstract The traditional approaches for improving corrosion resistance of alloys typically lead to the sacrifice of mechanical properties because the microstructures needed for improving corrosion resistance often contradict those for high strength.Here we demonstrate that selected laser melting (SLM), a net-shape additive manufacture technique, ca
