Numerical simulation provides a method to evaluate the CP effectiveness of HDD pipes. To improve the accuracy of potential distribution along the HDD pipe, it is necessary to adopt appropriate boundary conditions of the HDD pipe and accurate holiday models of coating. A specialized deep well polarization test device was designed and employed in the field to obtain the actual polarization characteristics as the boundary condition of the HDD pipe at buried depths ranging from 2 to 25 m. The result revealed that the polarization characteristics of HDD pipe in various depths were different and the potential distribution of the actual situation was greatly different from the potential distribution of the shallow aerobic soil. The potential distribution along the HDD pipe was analyzed in two types of holiday models. The results could be used as a reference for the CP effectiveness evaluation of HDD pipes.</div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 1","pages":"29-42"},"PeriodicalIF":1.6,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117811","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}

Pulse current cathodic protection technology, as an advanced pipeline corrosion protection technology, is superior to traditional cathodic protection technology. This paper mainly summarizes the research progress of pulse current cathodic protection technology for long-distance pipelines in recent years. It briefly discusses the protection mechanism, characteristic parameters, challenges, and development trends of pulse current cathodic protection technology, which provides a useful reference for the further promotion and application of pulse current cathodic protection technology for long-distance transport pipelines.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 1","pages":"20-28"},"PeriodicalIF":1.6,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.202414557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SMAs were subjected to two different electrolytes: saturated Ca(OH)2 solutions with and without chlorides to mimic the conditions in concrete. Two specific heat treatments were applied to the Fe-SMA, which resulted in a change in grain size and precipitation of secondary phases. Furthermore, conventional structural steel, B500B, was utilized as a reference material. The results reveal that the heat treatments did not significantly change the corrosion rates of these alloys in Ca(OH)2 solution compared to B500B when chlorides were absent. However, the presence of chloride ions suppressed the passivity of B500B and promoted the localized corrosion (pitting and intergranular) of the Fe-SMAs, among which the solutionized alloy showed significantly higher resistance to the pitting. It was demonstrated that the heat treatments and, consequently, microstructural characteristics influence the pitting behavior of these alloys.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 1","pages":"10-19"},"PeriodicalIF":1.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.202414562","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, engine components have been observed to corrode easily in biodiesels. In this study, a comparative study of the corrosion rate of aluminum coupon (AC) in biodiesel from waste cooking oil over chicken eggshell-supported alumina catalyst (WCOB) and fossil DF was executed. Weight loss method was used to examine the corrosion rate. Highest corrosion rates of 0.0381 and 0.0052 mm year−1 were recorded for AC in WCOB and DF, respectively. The developed mathematical models proved effective for corrosion rate prediction. At optimum prediction, the minimum corrosion rates for the AC in WCOB and DF were 1.822 × 10−3 and 1.222 × 10−3 mm year, respectively. Characterization revealed pits formation and presence of oxygen and carbon on AC surface with loss of Al ions from the AC surface into WCOB and DF after corrosion. In conclusion, all results revealed high corrosion rates of AC in WCOB than DF.","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 1","pages":"122-136"},"PeriodicalIF":1.6,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/maco.202414510","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
