What is it about?
This research looks at how to prevent a specific and dangerous type of corrosion—called crevice corrosion—in nickel alloys, which are widely used in demanding environments like chemical plants, energy systems, and nuclear facilities.

Why is it important?
Crevice corrosion happens in small, hidden gaps (for example, under gaskets or deposits) where the environment becomes aggressive over time. It’s hard to detect and can lead to unexpected damage or failure, even in materials that are normally very corrosion-resistant.
Perspectives
This work was motivated by a practical challenge: crevice corrosion remains one of the most difficult degradation mechanisms to predict and control in nickel alloys, even in environments where these materials are expected to perform well. Our results show that commonly considered inhibitors such as sulfate, nitrate, and molybdate do not behave universally—their effectiveness depends strongly on alloy composition, temperature and chloride content. I hope this study helps engineers move away from “one-size-fits-all” approaches and toward more informed, system-specific strategies for corrosion mitigation in critical applications such as energy and chemical processing.
