In this work, the surface oxide film growth behavior in low-oxygen atmosphere at 720 °C of two 12Cr heat-resistant steels with different Mn content was studied, and their corrosion resistance in liquid lead–bismuth eutectic (LBE) with saturated oxygen at 600 °C was tested. The results indicated that the pre-oxidized film of 1.6Mn steel is mainly composed of large-size Mn–Cr spinel and Fe–Cr spinel, while that of improved 0Mn steel is mainly composed of continuous and dense Cr2O3 and Fe–Cr spinel. This is because Mn has a high diffusion rate in Cr2O3, so it can pass through the Cr2O3 layer and combine with O to form Mn-rich oxides, and then the Mn-rich oxides react with Cr2O3 to form Mn–Cr spinel. However, due to the high solubility of Mn in LBE, the Mn-rich pre-oxidized film of 1.6Mn steel will dissolve and fail quickly, so its long-term corrosion resistance in LBE is lower than that of 0Mn steel.</div>","PeriodicalId":724,"journal":{"name":"Oxidation of Metals","volume":"101 4","pages":"729 - 754"},"PeriodicalIF":2.1,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140579181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout the years, several types of inhibitors and coatings have successfully been employed to reduce its devastating effects to a certain extent. In this study, two synthesized metal oxides namely Al2O3 and MnO2 were used as corrosion inhibitors and XRD, FTIR analysis were carried out to assess their structural properties. Further, TGA analysis for Al2O3 and MnO2 was carried out to determine thermal stability characteristics. The as-synthesized materials were further deposited as inhibitor coatings (Al2O3 with MnO2 bond coating, MnO2 coating and Al2O3 + 50% MnO2 coating) on T22 boiler steel specimens. All the specimens (bare T22 and coated T22 steel) were investigated for hot corrosion studies in Na2SO4-60%V2O5 environment at the temperature of 900 °C for 50 consecutive cycles. Every cycle involved a 1-h heating step in furnace followed by 20-min cooling at room temperature. Weight gain data were collected using a digital balance. XRD and (SEM–EDS) analysis were carried out to characterize the samples after exposure to hot corrosion environment. A better resistance to hot corrosion was observed for all the different types of coatings, with Al2O3 + 50% MnO2 coating representing maximum resistance.

While the oxide layers of the 0B sample from top to bottom were divided into four layers: Fe-rich oxide layer, MoO3 layer, Cr–Mn–Ni spinel oxide layer, and Cr2O3 layer (loose and porous), thus the undense Cr2O3 layer in the 0B sample can hardly inhibit MoO3 volatilization, especially at 1100 °C. In addition, the synergistic effect of B and Y on the diffusion of Cr to the surface was calculated using first-principles calculations. The results demonstrated that both the addition of B and Y can enhance Cr diffusion to the surface, while Y can specifically promote the combination of Cr and O.
