Areas of Research

The general focus of my research group is corrosion and high temperature oxidation of metals, with specific interest in metals and alloys used for components in nuclear power plants.  Research in my group involves evaluating corrosion susceptiblity of materials using high temperature fracture/corrosion tests and electrochemical measurements in conditions relevant to industrial applications (e.g. nuclear).  Knowing that corrosion of metals and alloys is generally thought to occur through nano-scale mechanisms, we apply cutting-edge microscopy techniques to perform post-exposure examination of corrosion and degradation from the micro-to-atomic scale.  The ultimate goal is to translate our developed mechanistic understanding of materials degradation into mitigation strategies and/or novel materials.

See the video below for a summary of research interests and a few neat examples!  

Laboratories and Research Projects

My group works closely with other nuclear materials professors and laboratories.  In particular, we maximize the use of the Reactor Materials Testing Laboratory (RMTL) supported by an Industrial Research Chair (IRC) (Prof. Daymond):  State-of-the-art proton accelerator, nano-indentation, and microscopy facilities are available!  

The corrosion laboratory is currently in progress as an expansion of the nuclear materials group/RMTL; facilities may include: 

    • High temperature and pressure static autoclaves and flow loops (aqueous)
    • Small modular reactor (SMR) corrosion facilities - molten salt and/or liquid Pb corrosion
    • High temperature oxidation atmospheric pressure reactor.
    • Necessary wet laboratory equipment (e.g. glassware, electrochemical cells, metallography, etc.).

Research Projects:

I am actively seeking Master and Doctoral students with interest in developing multi-disciplinary skills applicable to corrosion of materials, and seeking to analyze materials at the nano-scale!  Some potential project areas for students to consider include:

    • Stress corrosion cracking (SCC) of nickel alloys in aqueous environments.
    • Irradiation-assisted SCC of stainless steels.
    • Corrosion in aggressive environments relevant to SMRs.
    • High temperature oxidation of model alloys.
    • Development of oxidation-resistant materials (e.g. Fe-Cr-Al) for high temperature applications.
    • High temperature hydrogen attack/creep cracking of carbon steel.
    • Gaseous oxidation of nickel alloys at intermediate temperatures.

I seek interested students in science and engineering (materials, mechanical, chemical, physics are preferred). Many projects will involve collaborating with and/or presenting to interested industrial parties.
