Etude de carbures, nitrures et carbonitrures de fer élaborés par pulvérisation de fer élaborés par pulvérisation cathodique

Abstract : Three nitrogen-rich new cubic phases were recently discovered in the Fe-N system. As the Fe-N and Fe-C systems have joint structures, it can be considered the formation of new structures in the Fe-N-C system. These three systems are explored by preparing, in a large field of composition, coatings by sputtering. The coatings were characterized structurally and chemically with the help of XEDS, SNMS, Castaing probe, XRD, TEM, EELS and SEM. The carbon-rich Fe-C coatings possess a nanocomposite structure. The nitrogen-rich Fe-N coatings rich are mixtures of the cubic g'' and g''' phases and of a no-referenced phase, called X. Carbon addition involves the disappearance of these phases to the profit of the Fe2(N,C) phases. The g'' and g''' nitrides were isolated, which made it possible to determine the structure of g''', together with the characterization of their microstructure, the influence of oxygen A cubic g'''-Fe(N,C) carbonitride was highlighted
