中文摘要: 本文通过FSAM技术成功获得了6082-T6铝合金增材块，并对其耐腐蚀性能开展研究。结果表明：通过剥落腐蚀评级与静态失重法均说明增材体的耐腐蚀性能优于母材；动电位极化曲线与浸泡腐蚀试验也说明增材体较于母材，其腐蚀倾向与腐蚀速率较低，沿增材高度方向自下而上，腐蚀倾向与腐蚀速率呈逐渐降低趋势；6082-T6铝合金经过FSAM后，其粗大带状晶粒转变为细小等轴晶粒，强化相（Mg2Si相）数量减少且分布均匀，二者是导致增材体耐腐蚀性能高于母材的主要原因。

Abstract:In this paper, 6082-T6 aluminum alloy additive block was successfully obtained by FSAM technology, and its corrosion resistance was studied. The results show that the corrosion resistance of the additive is better than that of the base material by both spalling corrosion rating and static weight loss method. The potentiodynamic polarization curve and immersion corrosion test also show that the corrosion tendency and corrosion rate of the additive are lower than that of the base material, and the corrosion tendency and corrosion rate gradually decrease from the bottom up along the direction of the additive height. After FSAM, the coarse zonal grains of 6082-T6 aluminum alloy are transformed into fine equiaaxial grains, and the amount and distribution of Mg2Si phase are reduced and uniform, which are the main reasons for the corrosion resistance of the additive body is better than that of the base metal.
