Description |
Three different microstructures, Widmanstatten structure, acicular martensite, and alpha-plates, have been produced through suitable heat treatments for alloy Ti-6Al-2Sn-4Zr-2Mo (0.1 Si). The influence of these microstructures on pitting corrosion in 1 M NaBr solution has been studied using polarization technique. It is found that the parameters, pitting potential (E(pit)) and protection potential (E(pp)), are significantly influenced by the heat treatment conditions. E(pit) increases in the order alpha-plate < Widmanstatten structure < acicular martensite, while in the case of E(pp), the value increases in the order Widmanstatten structure < alpha-plates < acicular martensite. The poor E(pp) value in the case of Widmanstatten structure is attributed to the inherent variations in Mo and Al content between the plates accompanied by the formation of this phase.
