Low resistivity measurement of chromium coatings on zirconium alloys E110 for the production of accident-resistant core components of nuclear reactors

Abstract

Non-destructive testing (NDT) techniques, including thermal electromotive force (ThermoEMF) and four-probe resistivity (FPP) measurements, offer an innovative approach to assessing chromium coatings on zirconium alloy E110, which are utilized in the manufacturing of core components resistant to emergencies in nuclear reactors. These methods quantify their critical properties, such as electrical conductivity, thermoelectric stability, and coating uniformity, providing insights into the coating structural quality and adhesion.
