Abstract:Cobalt-based alloys are widely used for manufacturing of various components of gas turbine engines and gas turbines such as vanes and combustion chambers both in wrought state and as cast parts. They have been designed for improving the heat resistance due to solid solution and carbide-strengthening mechanisms. In order to obtain satisfactory oxidation resistance and hot corrosion resistance cobalt-based alloys are doped with sufficient amount of chromium (above 15 % wt.). Recently additive manufacturing has s… Show more
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.
