Abstract (en)
[origin: WO2015036974A1] The invention relates to a substrate characterised in that it is at least partially surface-coated with a coating containing at least one so-called "barrier" layer comprising silica and one or more material(s) X selected from among SiC, Si, Si3N4, in which layer the amount of X varies between 25 -wt.% and 50.-wt.% in relation to the total weight of the barrier layer, said barrier layer being formed by grains of one or more materials X covered at least partially in a silica shell, and said barrier layer being in direct contact with the substrate.
