As a result, this paper investigates the corrosion behaviour of 20# steel in produced water and 40% water content emulsion with different CO2 contents by combining Wire Beam Electrode (WBE) technology and the corrosion weight loss method, and establishes a corrosion mechanism model for analysis and explanation. The results demonstrate that variations in CO2 concentration have a greater impact on the corrosion process in the produced water simulated fluid, and there is considerable corrosion non-uniformity in the CO2 saturated state, as well as polarity reversal throughout the whole corrosion process. On the contrary, corrosion in the emulsion is more stable and uniform because the crude oil in the emulsion obstructs the mass transfer process of the depolariser agent and forms a ‘surface wetting’ effect on the metal surface, which seriously hinders the corrosion process.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"23 - 35"},"PeriodicalIF":1.8,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45236780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that the propagation of local active anodic dissolution at the steel inclusions could be totally inhibited by providing sufficient cathodic current in the sea water free of sand particles. However, the local ‘CP shielding’, potential fluctuation and sand impingements would enhance the anodic dissolution at inclusions, thus leading to the occurrence of erosion-corrosion under CP. The negative shift of the CP potential could not retard the propagation of erosion-corrosion pits under sand impingements. The synergy of erosion and corrosion might result in long-term failure of local CP.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"12 - 22"},"PeriodicalIF":1.8,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46875020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 10% pre-deformation substantially improves the SCC resistance of the 7075 alloys. The strain induced dislocations act as diffusion shortcuts and result in enhanced precipitation and early appearance of GBPs in the naturally aged 7075-T3. For artificial aging, pre-deformation causes rapid over-aging as larger precipitates are found in both matrix and GBs of the 7075-T8. The substitution of Cu for Zn in the GBPs and the larger GBPs acting as hydrogen traps are possible explanations for the improved SCC resistance of 7075-T8. Further improvements in SCC resistance can be found in the RRA treated 7075 alloys, while a more ductile behaviour can be seen in the pre-deformed 7075 alloy. Additionally, results of electrochemical testing are in high correlation with the SSRT results.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"57 1","pages":"774 - 788"},"PeriodicalIF":1.8,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49145668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PVA and its derivatives are associated with a proper combination of hydrophilicity and hydrophobicity, essential for effective anticorrosive activity. The present review aims to describe the past and present advancements in using PVA and its derivatives as aqueous and coating phase corrosion inhibitors. Bonding of PVA with the metallic surface in anodic, basic and neutral electrolytes has also been proposed along with their orientation. They become effective by adsorbing on the metal surface. They act as mixed-type inhibitors and create a barrier to the charge transfer process.
