    6093 Electrochemical Characterization in CO2 Saturated Environment of Zn-Rich Epoxy Nanocoatings on API X52 Pipeline Grade Steel Substrate under Flow Conditions

    Published: March 01, 2015
    Author(s): Violeta Valencia-Goujon Enrique Maya-Visuet, Homero Castaneda, The University of Akron; Todd Hawkins, Tesla NanoCoatings Inc.

    Here we aimed to electrochemically characterize a zinc-rich epoxy nanocoating primer (ZREP), as well as a composite variation incorporating carbon nanotubes (CNT-ZREP), on an API X52 pipeline grade steel substrate. A rotating cylinder electrode (RCE) was used to...
