The microstructures of the Cu/C and Cu/Al2O3 interfaces were characterised. The electrochemical corrosion behaviour of the composites was evaluated to study the influence of graphene content on the corrosion performance of the Cu matrix composites. The results showed that incorporating uniformly dispersed graphene with a small amount (∼0.25 wt-%) enables close integration with the Cu matrix, slows down the corrosion rate, and increases the impedance of the composites, thus effectively improving the corrosion resistance of Cu matrix composites. With an increase in graphene content (∼1.0 wt-%), defects tend to generate, leading to the formation of multiple corrosive microcell cavities in the composite, thus accelerating the corrosion of the composite. The Gr/Cu-0.25 composite exhibited better corrosion resistance in acidic, neutral, and alkaline corrosive solutions.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"145 - 155"},"PeriodicalIF":1.8,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41938411","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 value of D is used to describe the transition between the passive layers at the threshold temperature of 75°C; at which exhibits the largest stability. MMSS specimens passivated at 75°C exhibit higher passivity stability in experiments performed at 25°C, when compared the pre passivation, suggesting that the change experienced at 75°C is at least partially irreversible.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"156 - 168"},"PeriodicalIF":1.8,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49099118","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}

This corrosion mitigating tendency is enabled by the presence of electron clouds composed of lone pairs, pi-electrons, which allow them to be adsorbed over metallic equivalents. Because of the availability of nitrogen as heteroatoms, these compounds are being extensively used for corrosion diminution. This article looks at a variety of heterocyclic organic compounds like imidazole, triazole, pyridine, pyrazole, quinoline, tetrazole, pyrimidine, purine and pyrrole, having nitrogen as their prime constituent heteroatom for their anti-corrosive properties. The anti-corrosive properties of these nitrogen-based compounds in acidic conditions have been demonstrated using all available experimental techniques such as EIS, PDP and other theoretical investigations such as DFT and MD. Furthermore, the shift in the trend of these compounds inhibitory efficiencies has been noted and underlined here.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"73 - 101"},"PeriodicalIF":1.8,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46047223","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}

Friction stir welded joints exhibited a lower corrosion rate and degree of sensitisation compared to the base metal.

This work revealed the effects of inert solid deposits on the corrosion behaviour of Ti-2 in high acidity and highly oxidising leaching solutions. It was found that the deposit-covered Ti-2 had a higher corrosion rate (CR) than bare Ti-2. CR increased with increasing deposit thickness (up to 6 cm) and temperature. Solid deposits mainly affected the corrosion process of Ti by limiting the mass transfer of the oxidising Fe(III) from the bulk solution to the underlying Ti, thus affecting the stability of the protective passive film, and resulting in an accelerated passive CR. High temperatures and solid deposition are both commonly encountered in the hydrometallurgical industry, and their combination may significantly limit the maximum service temperature of Ti-equipment, implying that there is a risk in using Ti-components under such conditions.","PeriodicalId":10711,"journal":{"name":"Corrosion Engineering, Science and Technology","volume":"58 1","pages":"108 - 115"},"PeriodicalIF":1.8,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41398561","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}
