Abstract
The sealing composition contains powders composed, by weight, of 70 to 90% of aluminium, 5 to 25% of silicon, 0 to 5% of silica and 0.1 to 5% of moderating metal, which are dispersed in a vehicle comprising an organic binder dissolved in a solvent and a mineral binder. It is applied to the faces to be assembled of a ceramic part and of a refractory alloy or superalloy part and the whole is heated in order to eliminate said vehicle and form between the two parts a layer of mullite syncrystallized with the ceramic.
