A protective insulated coating (PIC) on 304 stainless steel (SS) surfaces as an IGSCC mitigation method was developed and investigated in high temperature water under various water chemistry conditions by measuring the electrochemical corrosion potential (ECP) and flow-assisted corrosion (FAC) rate. The ECP results clearly demonstrate that the PIC layer restricted oxidant transport to the metal surface, and the ECP remained at <−230 mV (SHE) in 288°C containing high oxygen (O2) and no hydrogen (H2). In this paper, long term durability of PIC layer prepared by various coating methods will be discussed.
