Buried Metal/Organic coating degradation
Our focus resides in using atomic hydrogen from one side of a substrate to polarise the inaccessible metal/coating interface on the other side. By leveraging Electrochemical Impedance Spectrocsopy (EIS), we capture the low- and high-frequency responses that signal the progress of oxygen reduction reaction (ORR) and breakdown of organic coating.
We are currently developing the Hydrogen Permeation based Potentiometry (HPP) technique, investigating how polymer coated industrial steels respond to hydrogen ingress.
Reliable Testing Methods
for Understanding Hydrogen Embrittlement Mechanisms
Transitioning to a hydrogen based economy involves developing reliable methods to measure hydrogen material interactions.
Using advanced characterization techniques, we investigate the effects of electrochemical hydrogen charging, hydrogen detection coating and steel microstructure to identify origin of artefacts in the determination of diffusion coefficient of hydrogen.
Tuning corrosion in temporary implants
Designing an implant that has mechanical properties close to that of the human bone, is biocompatible and degrades at an appreciable rate till the bone heals is challenging.
We investigate the potential of using a polymer coating with controllable pore density as a tool to modulate degradation rate of a magnesium alloy in conditions closely mimicking human physiology.
