The influence of heat input (HI) on the microstructure, microhardness, electrochemical corrosion performance cold metal transfer additively manufactured (CMTAM) nickel–aluminum bronze alloys was investigated. exhibited an α-Cu austenite matrix with minor γ2-Cu9Al4 and κ phases. As HI increased, microstructure coarsened progressively. Electron backscatter diffraction (EBSD) analysis revealed that increasing HI, grain size gradually increased Schmid factor increased. Consequently, microhardness declined from 198.3 HV to 171.7 HV. decrease in is primarily attributed coarsening uneven distribution phase. 243.8 J/mm 644.7 J/mm, current density rose significantly 2.56 ± 0.04 μA/cm2 7.52 0.07 μA/cm2. This result indicates a marked deterioration material’s resistance. phenomenon can be Al solute within microstructure. CMTAM hold significant potential for enhancing reliability long-term protection marine engineering equipment.
