In this study, the corrosion behaviours of Mg–3.4Y–3.6Sm–2.6Zn–0.8Zr alloy in 3.5 wt-% NaCl solution were investigated, the results suggested that the precipitations of rare-earth phase, (Mg, Zn)3(Y, Sm) and Mg12(Y, Sm) Zn, are beneficial to enhance the anti-corrosion of magnesium alloys. The network second phase, (Mg, Zn)3(Y, Sm), may act as an anode. It can form a galvanic couple with the adjacent α-Mg matrix and effectively protect the α-Mg matrix. The existence of the Mg12(Y, Sm) Zn phase makes the distribution of the (Mg, Zn)3(Y, Sm) phase more uniform, which may produce a more uniform electrochemical structure and reduce the galvanic corrosion. Under the dual action of the two second phases, the corrosion performance of Mg–3.4Y–3.6Sm–2.6Zn–0.8Zr alloy was better than that of the standard AZ31B alloy. The corrosion mechanism of the alloy is galvanic corrosion due to the second phase with low potential.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"57 1","pages":"613 - 624"},"PeriodicalIF":1.8,"publicationDate":"2022-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44483278","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 corrosion current i corr, the critical passivation current i cc, and the passive current i pass values increased significantly when the HCl concentration, scan rate, and temperature were raised. On the contrary, the addition of SCN− anions decreases the i corr value, indicating that the Ti dissolution was inhibited as a result of SCN− adsorption on the Ti surface. The inhibition efficiency increased with increasing the concentration of SCN−. However, SCN− anions lead to destabilised passivity in the passive zone.

As a general rule, polarisation coupons are installed close to the reference electrode to reduce the error in potential measurement. As a result, the error in the potential reading for close coupons is low. Still, the mentioned error has not been quantified due to the coupon's geometry, direction and non-linear polarisation behaviour complexity. In the present work, the IR-Drop error as a function of current density is extracted with generic calculation and simple assumptions, and the results are checked with three possible coupon-reference electrode arrangements. The proposed calculation could be used to extract the intrinsic error of polarisation coupons, regardless of their arrangement and coupon size. Moreover, it could be used to correct the measured potential and extract the true structure-to-soil potential.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"57 1","pages":"553 - 559"},"PeriodicalIF":1.8,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43458304","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}
