The electrochemical corrosion behavior of Ti-3Mo alloys under different accelerated corrosion tests including seawater corrosion, soil corrosion, and stray current corrosion was investigated. Results showed that the i corr value gradually increased with the increase of NaCl/Na 2 SO 4 concentration, indicating a worsening corrosion resistance of Ti-3Mo alloy. The presence of stray current seriously destroyed the oxide film on the sample surface, and inhibited the regeneration of oxide film, thereby resulting in the deterioration of corrosion resistance. Besides this, the potential difference between duplex phases was prone to form a microgalvanic coupling, which promoted the dissolution of local regions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
