The thermal spray coating technique was employed to produce insulated protective coatings (IPC) on 304 stainless steel (SS) surfaces. The electrochemical corrosion potential (ECP) response and flow-assisted corrosion (FAC) rate were then evaluated in high temperature water under various water chemistry conditions. The ECP results clearly
demonstrate that the IPC layer created with a powder of yttria-stabilized zirconia (YSZ) restricted oxidant transport to the metal surface, and the ECP remained at...
Key words: electrochemical corrosion potential, insulated coatings, boiling water reactor, noble metal, yittria-stabilized zirconia, high temperature water, plasma spray.
