Contact Angle & Electrochemical Measurements Of Metallic Atmospheric Corrosion On Copper And Carbon Steel, Jacob J.M. Bunting, Jiju M. Joseph, Heng-Yong Nie, Samantha M. Gateman

Undergraduate Student Research Internships Conference

Understanding atmospheric corrosion has been incredibly challenging due to the complex interplay between surface microstructures, environmental variables, and electrochemical processes. The methodology presented is being developed to apply to atmospheric corrosion models of metals and other advanced materials by observing the change in contact angle in situ as a function of corrosion parameters. Performed contact angle measurements on two industrially relevant metals (copper and carbon steel) over a 1 min to 30-day time span to track the change in wettability due to the formation of an air-formed oxide layer (aged) as a function of surface roughness.

Undergraduate Student Research Internships Conference

Scanning electrochemical microscopy (SECM) is a highly versatile method for measuring and imaging a wide range of systems. When paired with an intricately made ultramicroelectrode (UME) probe, SECM becomes an even more powerful tool for imaging microscale features in a system. However, purchasing these UME’s comes at a high cost with less ability for modification. Having high quality UME’s expands the ability of SECM and enables precise measuring and imaging in a wide range of applications such as solar cells in Dr. Ding’s lab, and corroding metals in Dr. Gateman’s lab. To combat this issue of high cost and set …
