RESEARCH

Metals play a vital role in our modern day society, but their tendency to corrode compromises their structural integrity, safety, and function. Advancements in corrosion prediction tools must be made to lower its economic and safety expenses. Dr. Gateman’s research highlights the importance of bridging the gap between analytical chemists, corrosion scientists, and industry through tailoring quantitative and spatially resolved electrochemical methods to investigate corrosion initiation mechanisms on the micro/nano scale under simulated in-service environments.

Scanning electrochemical probe microscopy (SEPM) is a collection of versatile methods capable of capturing micro electrochemical images and extracting local kinetic and topographic information of a substrate through measuring electrochemical reactivity at an ultramicroelectrode (UME) or through a micro/nanopipette. The effect of microscopic features (inclusions, grain boundaries, corrosion product, coating defects, etc.) on corrosion at a metal/coating interfaces in-situ using in-service solution chemistry can be realized using different SEPM techniques including scanning electrochemical microscopy (SECM), scanning micropipette contact method (SMCM), and localized electrochemical impedance spectroscopy (LEIS). Another research goal of ours will focus on advancing SEPM’s analytical figures of merit so that the techniques become standardized electro analytical tools in corrosion science.

Students will be trained in experimental methods including macro electrochemical techniques, scanning electrochemical probe methods, and various complementary analytical and surface characterization tools. If you have a passion for corrosion science and/or SEPM and are looking to join a collaborative, inclusive, and respectful team of people, please contact Prof. Gateman for available positions to become a part of our team.
