Immersion Characteristic by Organic/Inorganic Hybrid Solution Coating of Austenite Stainless Steel Degraded in 480-720oC

Abstract

This study was conducted to investigate the pitting resistance due to degradation of stainless steel (STS310S, STS316L and STS347H). The three types of non-heat treated specimens did not exhibit pitting regardless of whether or not a coating had been applied. In an acidic solution, the non-coated specimen and the OIBD-2 coated specimen of degraded stainless steel had pitting, but the OIBD-1 coated specimen did not have it at all. In an alkaline solution, all of the degraded specimens did not exhibit pitting at all.
