Abstract

Abstract

As the main structural material of new steam generator (SG), the crevice corrosion behavior of titanium alloy has been concerned. However, the crevice corrosion resistance of titanium alloy in boron and lithium media is less studied. In this paper, the crevice corrosion behavior of titanium alloys TA16 and TA17 in boron and lithium media for 5000 h was studied by means of micro corrosion loop. The crevice corrosion sensitivity of the two materials was obtained, and the composition and structure of the oxide film of titanium alloys were analyzed. The results show that no crevice corrosion is observed on the sample, which indicates that TA16 and TA17 are insensitive to crevice corrosion in boron and lithium media. There are some differences between the oxides inside and outside the crevice of titanium alloys, and the granular microcrystal FeTiO₃ outside the crevice is independent of crevice corrosion of titanium alloy.
