摘要：This study aims to solve the strength-corrosion trade-off by manufacture dissimilar aluminum alloy components via alternating deposition of Al-Mg alloy and Al-Zn-Mg-Cu alloys. The investigation focuses on analyzing the microstructural characteristics, mechanical performance, and corrosion behavior of the resulting components. The as-deposited alloy exhibits a distinct layered structure, comprising 5356 layers, interface region and 7075 layers. The interfacial transition region contains phases from both alloys, namely alpha-Al, Al3Mg2, Mg2Si, MgZn2, Al2CuMg, and Al3Fe. The sample exhibits higher ultimate tensile strength (273.6 MPa) and elongation (8.4%) in the horizontal direction than those in the horizontal direction (239.5 MPa, 4.4%). The average microhardness significantly increases from 5356 region to 7075 region. Fracture occurs in the interface transition area near 5356 region, with a mixed ductile and brittle model. The corrosion resistance of the sample lies between two individual alloys, exceeding AA7075 and approaching to AA5356. This study provides guidance for balancing strength and corrosion resistance of dissimilar aluminum alloy and the construction of multifunctional materials via WAAM.
