Enhancement of the formation of Fe16N2 on Fe films by Co additions (invited)
Abstract
Effects of Co additions on the formation of Fe16N2 have been investigated by observing nitrides formed on thin-film surfaces. Thin films of Fe-Co alloys with a (100) surface sputter-deposited on MgO(100) substrates are exposed to a mixed gas of NH3 and H2. The 16:2 nitride was observed to form on a surface of Fe-10 at. % Co film at a nitriding temperature of 500 °C. The formation temperature is 50 °C higher than for pure iron. The amount of the formed 16:2 nitride has been found to be 3× larger for Fe-10 at. % Co than for pure iron.
