Ceramic composite pipes were produced by a centrifugal‐exothermic process in a short time without the use of a high‐temperature furnace. The process is characterized by an exothermic reaction following a thermite reaction. The reactions occur under the influence of centrifugal force. Two‐layer ceramic pipes composed of molybdenum carbide or boride combined with aluminum oxide were produced using mixtures of MoO3, Al, and C or B powders.
A vacuum centrifugal‐thermite process was used to prepare ceramic‐lined pipes rapidly. The ceramic layer was dense, and the grain size was smaller than that produced under atmospheric pressure, resulting in improved mechanical properties.
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.
