The influence of La and Ce on the corrosion resistance of low-alloy steels was compared through indoor cyclic-immersion accelerated tests simulating tropical marine atmospheres. The corrosion mechanism of low-alloy steels with different La and Ce contents in simulated tropical marine atmospheres was investigated using electrochemical measurements and corrosion product analysis. The results show that La and Ce improve the uniform corrosion resistance of low-alloy steels. With increasing La\/Ce content, the corrosion current density decreased from 1.8936 \u00d7 10\u22126 A cm\u22122 for 0LaCe to 1.29 \u00d7 10\u22126 A cm\u22122 for 0.3LaCe, corresponding to a reduction of approximately 31.9%. This is attributed to the fact that La\/Ce addition promotes rust layer stabilization and densification, as suggested by the evolution of major rust phases and the presence of La\/Ce-related oxidized species. Meanwhile, alloying with La and Ce improves the cracking of the rust layer, reduces the number of pores, and stabilizes the rust layer structure.<\/jats:p>","DOI":"10.3390\/ma19122685","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T08:19:52Z","timestamp":1782202792000},"page":"2685","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect
