ICMT student receives an award from ConocoPhillips

Jing Ning, a PhD student, has received a "Job Well Done!" award from ConocoPhillips for the work done during her internship at the COP last year. Her internship was done in the Corrosion, Inspection & Material group at COP, and Jing's internship project focused on introduction of a technique novel to the corrosion studies - use of Scanning Electrochemical Microscope (SECM) in corrosion studies, and investigation of the effect of corrosion inhibition on the mitigation of preferential weld corrosion. A paper of this work titled “Effect of Corrosion Inhibition on the Mitigation of Preferential Weld Corrosion in Seawater Transpor” will be published at NACE 2015.

Abstract of the work:
Conventional electrochemical measurements carried out in corrosion laboratory, such as linear polarization resistance and electrochemical impedance spectroscopy, can only provide an overall average corrosion rate at the metal-electrolyte interface. The SECM has been increasingly used for in-situ electrochemical investigations due to its high spatial resolution at a microscopic level, therefore, enabling a closer look at the corroding metal surface. However, the exercise of introducing the SECM technique to corrosion assessment is still in its infancy due to many limitations present in the complex corroding systems. In this study SECM was introduced, explored and applied to investigate preferential weld corrosion. In addition, SECM technique was deployed to study the effect of corrosion inhibition on PWC mitigation.
