Abstract:Abstract:The influence of alloying element S, Se or Te on the oxidation resistance of pure Cu was studied by oxidizing in 0.1 MPa pure oxygen atmosphere at 573-873 K in comparison with a 6N Cu (99.9999 wt.%). The addition of S, Se or Te is found to improve the oxidation resistance of Cu remarkably. This improvement is contributed from the accumulation of alloying element at the Cu 2 O/Cu interface and segregation of alloying elements at grain boundaries in Cu 2 O.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
