Abstract

The original scope of this work was to advance the understanding of corrosion properties of additively manufactured (AM) materials by correlating microstructural defects in AM materials to the material conventional counterparts utilizing a scanning kelvin probe [Ametek VeraSCAN Electrochemical System]. However, upon the initiation of project research, it was observed that the system was not operational due to unknown hardware and software problems. The evolved scope of this work was to reconcile the operational issues and develop a repair and mitigation plan. After extensive troubleshooting, it was determined that the software was not properly configured, and the electrometer had permanently malfunctioned. A repair plan was developed, with identified malfunctioning components, with a manufacture quoted $2,152.50 repair cost. Several mitigation steps are also recommended, to avoid additional issues and hardware concerns. With the successful repair and use of the VeraSCAN system, the university will greatly benefit from the full functionality of this electrochemical system. If the stated plan is executed, future students will be able to successfully complete the original scope, and benefit the Corrosion Engineering Program, and Department of Chemical and Bimolecular Engineering.
