a b s t r a c tFe-and Ni-base alloys including an alumina-forming austenitic alloy were exposed for 500 h under metal dusting environments with varying temperature, gas composition and total pressure. For one H 2 -CO-CO 2 -H 2 O environment, the increase in temperature from 550 to 750°C generally decreased metal dusting. When H 2 O was added to a H 2 -CO-CO 2 environment at 650°C, the metal dusting attack was reduced. Even after 5000 h at a total pressure of 9.1 atm with 20%H 2 O, the higher alloyed specimens retained a thin protective oxide. For gas mixtures containing little or no H 2 O, the Fe-base alloys were less resistant to metal dusting than Ni-base alloys.
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.
