The structure and molecular weight of modified epoxy resins (MEP) were characterized by proton nuclear magnetic resonance and gel permeation chromatography. A dynamic light-scattering particle size analyzer was used to study the particle size of WEP emulsions. When we studied the properties of coatings, the results showed that WEP-19:1 had small particle sizes and the best comprehensive properties. The salt spray resistance time was more than 480 h, which indicated that the coating had effective corrosion resistance.","PeriodicalId":18728,"journal":{"name":"Materials Performance","volume":"63 5","pages":"34-37"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147922979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, in order to reduce the water absorption of an anticorrosive coating substrate to meet the requirements of heavy-duty exposure, a new method of modification of the epoxy resin with polysulfide rubber was explored. The results of mechanical properties, water resistance, and electrochemical impedance spectroscopy tests showed that the water resistance and mechanical and corrosion properties of the matrix prepared by the new modification method were significantly improved.","PeriodicalId":18728,"journal":{"name":"Materials Performance","volume":"60 11","pages":"40-43"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, an increasing number of corrosion failures on these pipelines have resulted in the need to analyze their cause and take proactive measures. This paper reviews comprehensive failure evaluations and overall ductile iron pipeline evaluations that provide critical data regarding the anticipated remaining life of the water main and the probability of future failures. Informed decisions relevant to pipe rehabilitation and replacement programs can be formulated, lessons regarding the installation of more corrosion resistant replacement pipelines or pipe sections can be learned, and resources can be effectively directed to high risk areas in the water system.","PeriodicalId":18728,"journal":{"name":"Materials Performance","volume":"42 1","pages":"115-129"},"PeriodicalIF":0.0,"publicationDate":"2003-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1061/40690(2003)25","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58571340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The iron-nickel-chromium alloys suffered severe metal dusting after a very short test period. Nickel-based alloys were generally less susceptible to metal dusting than iron-based alloys. Nickel-based alloys with chromium concentrations of 25% and above, on the other hand, showed no significant evidence of metal dusting even after 10,000 h of exposure. It was found that these alloys were protected against metal dusting by the formation of a dense, self-healing chromia scale, which prevented the penetration of carbon into the base metal.","PeriodicalId":18728,"journal":{"name":"Materials Performance","volume":"4 5","pages":"58-63"},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50695778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
