Development of suicide coatings to ensure the protection of Nb and suicide composites against high temperature oxidation
Abstract
International audience ; In this work, we describe the fabrication of coatings containing (TiNbXCr)(7)Si-6 silicide (with X = Fe, Co and Ni) by halide-activated pack-cementation on Nb and silicide composites. The coating oxidation performance is evaluated isothermally at temperatures ranging from 1100 degrees C to 1300 degrees C and cyclically at 1100 degrees C In all the coating systems examined, the M7Si6 suicide formed in the protective coating and constituted the outmost layer for coatings containing Co, whereas M6Si5 and a Cr-rich suicide constituted the outmost compounds for Fe and Ni coatings, respectively. The results of isothermal oxidation tests show that all these compounds form protective oxide layers leading to very low mass gains, both at 1100 degrees C and 1200 degrees C. Under cyclic conditions at 1100 degrees C, coatings containing Co and Ni exhibited very long lifetimes, exceeding 2600 1-hour cycles. The beneficial effect of Ni and Co diminished at 1300 degrees C, due to rapid interdiffusion between substrate and coating in comparison to that found in the Fe containing coating.
