Abstract
A method includes coating of one or more zones of the refractory alloy part, using a treatment composition including one or more types of preceramic polymer, a solvent and one or more active fillers, and heat treating the coated refractory alloy part, the heat treatment allowing to partially convert the preceramic polymer to form a ceramic layer, the active filler forming on a surface of the refractory alloy part, one or more ternary alloys and forming a continuous layer between the surface of the refractory alloy part and the ceramic layer obtained by conversion. The heat treatment forms a continuous layer of the ternary alloy. The treatment composition includes, relative to the total weight of the treatment composition, a weight proportion of between 40% and 66% of the one or more active fillers, and an active filler/preceramic polymer weight ratio is greater than or equal to 2.
