This study evaluates corrosion performance of additively-manufactured metal alloys, specifically LPBF, for Naval applications. Samples manufactured in horizontal, vertical, and 45° orientations underwent corrosion testing in artificial seawater, comparing performance before and after surface preparation. Microstructural analysis via Scanning Electron Microscope (SEM) complemented electrochemical measurements. Results demonstrate the clear influence of build orientation and surface roughness on corrosion behavior and compare LPBF materials against traditional wrought counterparts, providing critical insights for Naval component manufacturing.
