Resumen

The electronic structures of native oxides formed on Fe-15Cr, Fe-5Al and Fe-15Cr-5Al (all in wt.%) alloys, and the corresponding effects on diamond nucleation and growth in plasma enhanced CH₄-H₂ atmosphere were investigated. The ambient environment exposure produces a mixed surface oxide layer containing the oxides of both Fe and Cr or Al on Fe-15Cr or Fe-5Al alloys, respectively. A selective oxidation of Al occurs on Fe-15Cr-5Al and it protects the other two substrate elements from oxidation. The diamond deposition behavior indicates that prior to diamond growth, a graphite intermediate layer preferentially forms on Fe-15Cr and Fe-5Al alloys, along with an internal carburization of the substrates. For Fe-15Cr-5Al, only a single diamond coating with enhanced interfacial adhesion is produced, which is attributed to the effective barrier property of the aluminum oxide passive layer.
