Abstract
As ammonia does not emit greenhouse gases when burned, it is considered a fuel instead of fossil fuels. However, there are few reports on the corrosion behavior of materials when ammonia is used as fuel. Therefore, this study measured the hydrogen produced by the reaction between ammonia and iron using a hydrogen sensor containing a proton conductor. As a result, the amount of hydrogen produced by the decomposition of ammonia was small at low temperatures but increased at high temperatures. Also, when the ammonia content was low, oxidation of iron occurred preferentially. This way, the relationship between the amount of hydrogen generated and corrosion behavior could be clarified.
期刊介绍：
Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
