Corrosion and aging of organic aviation coatings: A review

Organic anticorrosive aviation coatings are an effective guarantee for aviation structure, since aircraft corrosion can lead to great economic losses. Whether it is during ground parking or air cruises, organic aviation coatings are important barriers to the corrosion of aviation structure. With the vigorous development of the aviation industry, organic aviation coatings continue to meet the challenges of diverse, complex, and harsh service environments. This review analyzes and summarizes the research status of the types and development of organic aviation coatings, influencing factors and mechanisms, experimental methods, calendar life research methods, and modification methods. It also summarizes the research results that have been achieved to date. The current research deficiencies in the equivalence relationship between atmospheric exposure and artificial acceleration, failure criteria and life prediction were pointed out, and nano-modification technology, and future research strategies and directions that need breakthroughs are discussed.
