“…Corrosion fatigue often begins with microscopic defects or stress concentrators in the material [158]. In a corrosive environment, the material surface may be attacked by chemical agents, forming corrosion pits or localised corrosion [159]. When the material is subjected to cyclic mechanical loading, it introduces alternating stress on the material, which leads to the initiation and propagation of cracks from the stress concentrators or corrosion pits [160].…”

Aluminium alloys have been integral to numerous engineering applications due to their favourable strength, weight, and corrosion resistance combination. However, the performance of these alloys in coastal environments is a critical concern, as the interplay between fracture toughness and fatigue crack growth rate under such conditions remains relatively unexplored. This comprehensive review addresses this research gap by analysing the intricate relationship between fatigue crack propagation, fracture toughness, and challenging coastal environmental conditions. In view of the increasing utilisation of aluminium alloys in coastal infrastructure and maritime industries, understanding their behaviour under the joint influences of cyclic loading and corrosive coastal atmospheres is imperative. The primary objective of this review is to synthesise the existing knowledge on the subject, identify research gaps, and propose directions for future investigations. The methodology involves an in-depth examination of peer-reviewed literature and experimental studies. The mechanisms driving fatigue crack initiation and propagation in aluminium alloys exposed to saltwater, humidity, and temperature variations are elucidated. Additionally, this review critically evaluates the impact of coastal conditions on fracture toughness, shedding light on the vulnerability of aluminium alloys to sudden fractures in such environments. The variability of fatigue crack growth rates and fracture toughness values across different aluminium alloy compositions and environmental exposures was discussed. Corrosion–fatigue interactions emerge as a key contributor to accelerated crack propagation, underscoring the need for comprehensive mitigation strategies. This review paper highlights the pressing need to understand the behaviour of aluminium alloys under coastal conditions comprehensively. By revealing the existing research gaps and presenting an integrated overview of the intricate mechanisms at play, this study aims to guide further research and engineering efforts towards enhancing the durability and safety of aluminium alloy components in coastal environments.

“…Surface analysis in this type of research is of paramount importance because the properties defined by the microstructure are closely linked to device performance. The images obtained by microscopy help to understand the composition, morphology, and dynamic behavior of these types of coatings, which are fundamental for the quality control of products and the development of new materials [2,6,10]. Unfortunately, the specialized equipment used to measure the microstructural properties is expensive and might not be available in some laboratories.…”

Electrodeposition is commonly employed to coat materials. The effectiveness and endurance of coatings depend on specific process conditions. The characterization of coatings is a costly endeavor, requiring specialized knowledge and expertise. This study presents a novel methodology for analyzing surfaces coated with copper, utilizing computer vision techniques to complement traditional surface characterizations such as the contact angle. The coating under investigation was produced through electrodeposition using a ChCl:2EG:0.1CuCl2·2H2O electrolyte. Our findings demonstrate the feasibility of the vision-based method for evaluating superficial copper electrodeposition on sandblasted 304 SS. The proposed vision method holds the potential to expedite the development of new coatings and facilitate the analysis of their characteristics. This, in turn, could enhance the durability of materials and devices across a range of applications.
