The unique combination of the properties of iron aluminides opens up a multitude of novel applications at elevated temperatures in oxygen and sulphurous atmospheres. FeAl composites have excellent wear and corrosion resistance paired with the intermetallic phases of the Fe-Al system, which, however, tend to hydrogen embrittlement. In this paper, intermetallic phases are produced from FeAl using the self-propagating high-temperature synthesis process, which is reinforced with inclusions from other intermetallic phases, which prevent cracks from spreading. In addition, layers are deposited by means of thermal spraying, which are analyzed with regard to their composition and structure. Paper includes a German-language abstract.
