“…Three replicas were employed to determine the weight loss, and the remaining one was used to analyze the corrosion morphology and the corrosion products. Table 2 lists the annual average environmental parameters and atmospheric pollutants measured at Xisha islands during the exposure, which is consistent with the description in our previous work [16]. The annual average temperature in Xisha marine atmosphere was 27 ∘ C with the maximum temperature increasing up to 33.3 ∘ C and the minimum temperature reducing to 20.1 ∘ C which was also a relatively high temperature.…”

Atmospheric corrosion behavior of 2A12 aluminum alloy exposed to a tropical marine environment for 4 years was investigated. Weight loss of 2A12 alloy in the log-log coordinates can be well fitted with two linear segments, attributing to the evolution of the corrosion products. EIS results indicate that the corrosion product layer formed on the specimens exposed for 12 months or longer presents a good barrier effect. Corrosion morphology changes from pitting corrosion to severe intergranular corrosion with the extension of exposure time, resulting in the reduction of the mechanical properties.

Atmospheric corrosion behavior of 7A04 aluminum alloy exposed to a tropical marine environment for 4 years was investigated by weight loss test, morphology observation, and electrochemical impendence spectroscopy (EIS). The results showed that the weight loss of 7A04 alloy in the log-log coordinates can be approximately fitted with two liner segments, in which the slope value of the second segment is significantly lower than that of the first segment. This was mainly attributed to the protectiveness of the corrosion product layer formed on the specimen exposed for 12 and 24 months, which was further confirmed by the EIS results. Corrosion rate presented a significant fluctuation during the exposure test which is due to the deterioration effect caused by chloride ions and time of wetness and the stabilization process of the corrosion product layer. Intergranular corrosion occurred on the 7A04 alloy and then transformed into exfoliation corrosion because of the synergetic effect of the hydrogen-assisted crack initiation and the wedge effect-induced matrix delamination.

Zn coated steel (Z) and ZnAlMg coated steel (ZM3.7/3 = Zn–Al (3.7 wt.%)‐Mg (3.0 wt.%)) have been exposed for 6 years at twelve different weathering sites world wide. The mass loss of the coatings have been measured after 1, 2, 4, and 6 years exposure. From the results, it is shown that ZM3.7/3 had always a better corrosion performance compared to Z. The ratio of performance after 6 years of exposure varied from about 1.4 to 4.4 with a mean value of 2.8. At temperate marine sites (e.g., temperature between 9–20°C) with low to moderate SO 2 pollution a good relationship was observed between the relative performance of ZM3.7/3 and the corrosion rate of Z. It was thus concluded that ZM3.7/3 has a better relative performance in harsh environments. The corrosion performance of ZM3.7/3 was shown to be connected to the formation of protective corrosion products.
