“…SVET was used to study the localised corrosion characteristics and the relative corrosion performance. It is a powerful technique in corrosion research and has been employed in a range of investigations, such as galvanic corrosion, pitting corrosion, corrosion inhibitors, stress corrosion cracking, and cut-edge corrosion 4,15,16,21,22,[34][35][36][37] . The samples were prepared as mentioned in section 5.2.1 though they were not etched.…”

Time-lapse Microscopy, scanning vibrating electrode technique and potentiodynamic methods were used to study the influence of increasing coating weight (80-310 gm-2) on microstructure, cut-edge and surface corrosion of Zn-Mg-Al coatings in 0.17 M NaCl. Cut-edge corrosion was similar for all coating weights due to the ORR becoming diffusion-limited. A 64% reduction in surface corrosion was observed for high coating weights through increases in eutectic volume fraction. Spatial and temporal corrosion mechanisms were controlled by microstructural morphological differences as coating weight varied. 80 g.m-2 coatings demonstrated lateral anodic spreading potentially reducing coating penetration rates despite their higher surface corrosion rate.

“…Generally, surfaces possess excellent corrosion resistance, and their corrosion mechanisms have been largely elucidated. In contrast, cut-edge corrosion has a metal-exposed surface in direct contact with the surrounding environment, making it easy for the main factors of corrosion, air and moisture, to come into contact [13,14]. Moreover, galvanic corrosion due to potential differences with surface coatings can occur [15].…”

This study explores the self-healing phenomenon at the cut edges of Zn-Al-Mg alloy coated steel in chloride environments, a critical consideration for materials exposed to marine conditions. Zn-Al-Mg coatings offer superior resistance to cut-edge corrosion. This research aims to unravel the self-healing properties observed in these coatings. Through cyclic corrosion tests (CCTs), we compared the corrosion resistance of Zn-Al-Mg coated steel with traditional zinc alloy coatings. Our findings show a notable reduction in corrosion with ZMA4 coatings after 120 CCT cycles. This is due to the formation of corrosion products, namely layered double hydroxides (LDHs) and Mg(OH)2. X-ray diffraction and X-ray photoelectron spectroscopy analyses were employed to confirm the presence of these products and elucidate their roles in the self-healing process. This study highlights the potential of Zn-Al-Mg coatings for enhancing the durability of steel structures in corrosive environments, suggesting a paradigm shift in corrosion protection strategies for marine applications. The development of coatings that exhibit self-healing capabilities in chloride-rich environments could significantly mitigate the challenges posed by cut-edge corrosion, promising extended service life and reduced maintenance costs.
