摘要

抗腐蚀敏感性是选择用于多种工业应用的金属材料的首要标准之一。本工作研究了通过重复波纹和矫直（RCS）获得的Al-7075合金的腐蚀性能。这种加工方法产生了由随机分布的微米、亚微米和纳米晶粒尺寸形成的微观结构。样品在电解质中的耐腐蚀性在更长的时间内下降，变形更大。然而，与非变形条件相比，RCS处理的样品显示出更好的电化学稳定性。电化学稳定性的提高可能与RCS过程中产生的特定微观结构有关。

Repetitive corrugation and straightening effect on the microstructure, crystallographic texture and electrochemical behavior for the Al-7075 alloy

Anti-corrosion susceptibility is one of the top criteria for selecting metallic materials for several industrial applications. This work studies the corrosion performance on an Al-7075 alloy obtained by Repetitive Corrugation and Straightening (RCS). This processing method generated a microstructure formed by randomly distributed micro-, submicro-, and nano- metric grain sizes. The samples exhibited a drop in corrosion resistance for a longer duration in the electrolyte and higher deformation. However, the samples processed by RCS showed better electrochemical stability in comparison with the non-deformed condition. The improvement of electrochemical stability could be associated with the particular microstructure generated during the RCS process.
