Abstract:

Corrosion research at the University of Wisconsin is focused on two areas i plasma-based surface treatments to reduce corrosion, ii high temperature corrosion in harsh environments. Plasma-based surface treatments 10 to 2000nm depth have involved ion implantation and thin film deposition and atomic mixing approaches to mitigate corrosion and wear. Specific testing equipment for corrosion testing in high temperatures and harsh environments such as supercritical water, molten salts, supercritical carbon dioxide KAPL, and helium have been designed and built. Room temperature corrosion tests for potentiodynamic corrosion tests, impedance spectroscopy, and salt spray test facilities exists and are being used for research in conjunction with a suite of materials characterization techniques. Research projects involve the development of a basic understanding of corrosion mechanisms as well as strategies such as surface treatments and grain boundary engineering to mitigate corrosion.
