In the present study, isolated particle healing (IPH) treatment was proposed to eliminate these isolated particles. Then, the related structure evolution and oxidation kinetics of Si coatings were investigated. Finally, the failure mechanism of TGO after oxidation was identified. The results show that the IPH treatment makes isolated particles diffuse, connect with and then immerse themselves into the bulk coating surface, thereby contributing to both surface smoothing and coating densification. Consequently, the localized large thickness in the TGO scale is eliminated, and the overall oxidation rates of the IPH Si coating decrease by ∼24% compared with the as-sprayed coating. The β→α phase transformation of polymorphic cristobalite with a volume reduction of ∼4.5% is the main cause for TGO channel cracking and is not suppressed by IPH treatment, which points out future directions for better antioxidant Si coatings.</div>","PeriodicalId":100337,"journal":{"name":"Corrosion Communications","volume":"8 ","pages":"Pages 9-17"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667266922000470/pdfft?md5=a265de78b3c5f110af5ea45d1d04c08f&pid=1-s2.0-S2667266922000470-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92083147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results demonstrate that both the planktonic and sessile IOB caused the corrosion of X65 steel by promoting the oxidation of ferrous ions, but the contribution of sessile cells was far greater than that of planktonic cells. Cathodic polarization kills sessile cells on the metal surface and prevent attachment of IOB. With a negative shift of the cathodic potential, the inhibition effect was enhanced. Cathodic polarization altered interface properties of X65 steel, affecting adhesion and corrosion process of IOB cells. However, when X65 steel was sufficiently polarized to −1050 mV vs. SCE, IOB produced more extracellular polymeric substances to resist stimulation by an external electric field.
