Abstract

The issue of corrosion failure in offshore wind turbine steel pipe piles has become increasingly evident, posing a significant threat to the safe operation of offshore wind energy systems. To address this, the applicability of light-curable anti-corrosive coatings in tropical marine atmospheric conditions was investigated in this study. Firstly, the bending and tensile properties of the light-curable composites were tested. Then, salt spray tests, as well as acid and alkali resistance tests, were carried out on the light-cured sheets. Results showed that the mechanical properties and neutral salt spray (NSS) resistance of the light-curable materials were excellent, and their resistance to neutral salt spray was found to be comparable to that of Anshun armor. In H2SO4 and NaOH solutions, the weight gain rate of the light-curable materials was found to be less than 1.2%, the hardness variation rate was less than 8%, and the bending strength retention rate exceeded 92%, demonstrating its excellent acid and alkali resistance. The light-curable materials met the requirements of anti-corrosion materials for offshore wind power equipment.
