This study investigates the corrosion performance of nano-treated AA7075 alloys and reveals that nano-treating enhances the corrosion resistance of the material, particularly localized corrosion resistance. The interplays among microstructures, oxidation passivation, and corrosion were also highlighted.
High-strength Al alloys like Al-Zn-Mg-Cu series are susceptible to corrosion attacks. Nano-treating is an emerging metallurgical method to enhance their performance. However, there lacks an understanding of nanoparticles' effects on their corrosion. In this study, corrosion performance of two nano-treated cast and extruded AA7075 alloys (with TiC and TiB2) was investigated. Their dynamical corrosion characteristics on freshly exposed, passivated, and immersed surfaces were compared. The interplays among microstructures, oxidation passivation, and corrosion were revealed. The results show nano-treating enhances corrosion resistance of AA7075, partic-ularly localized corrosion resistance. This study has advanced the multi-scale understanding of corrosion in nano-treated AA7075.
