In this work, the corrosion behavior of marine engineering materials in three typical harsh marine atmospheric environments is investigated i.e., the so called "Antarctic low-temperature and high-irradiation ice-snow freezing-melting environment", "high-temperature, high-humidity and high-salt fog atmospheric environment of South China Sea", and "coastal chlorine-haze coupling environment". The results show that in Antarctic environment, the electrochemical corrosion process can occur even beneath the cover of snow and ice at extremely low temperature. The freezing-melting process of ice and snow leads to the existence of surface electrolyte film for a long period, which promotes the corrosion reactions and accelerates the localized corrosion. In the environment of the South China Sea, there is a synergistic effect of chemical oxidation and electrochemical corrosion on the surface of non-ferrous materials in high humidity and high Cl^- atmospheric environment at high temperature. Different aluminum alloys have different corrosion initiation and propagation driving forces (i.e., diffusion and charge transfer, hydrogen-induced intergranular cracking, and wedging effect of corrosion products). The synergistic effect of time of wetness (TOW) and Cl^- content lead to the deviation of corrosion dynamics from the power function. In the coastal chlorine-haze coupling environment, the key controlling factor of NH₄⁺ in acceleration of corrosion in the chlorine-haze environment is the continuous supply of H⁺ caused by the buffering effect of NH₄⁺. Meanwhile,“quasi auto-catalytic pitting” corrosion occurs because of the synergistic effect of Cl^-, NO₃^-, and NH₄⁺.
