Experimental and ab initio investigations into the fundamentals of corrosion, in the context of supercritical water oxidation systems
… to even noble metals and the most advanced alloys. Corrosion in chlorinated, acidic streams at transitional temperatures (100-400° C) in a Hastelloy C-276 tube is examined through post-failure analysis and controlled exposure experiments. Dealloying and intergranular corrosion were observed. …

Corrosion and Tribocorrosion Kinetics of Al-based Concentrated Alloys in Aqueous Sodium Chloride Solution
Commercial aluminum (Al) alloys are often precipitation strengthened to improve strength and wear resistance. However, localized corrosion due to the galvanic coupling between the precipitates and Al matrix often leads to degraded performance when these alloys are exposed to corrosive environment. …
