“…coatings display good intrinsic thermal stability due to their high activation energy and extremely low parabolic rate constant of oxidation [11,17]. However, the degradation of SiMeN is determined by the interfacial diffusion/reaction with the underlying substrate as the interdiffusion/inter-reaction could alter the microstructure and chemical composition of the top amorphous SiMeN coating, or cause the depletion of the remnant SiMeN coating [11,17,20].…”
