摘要
The protection against wear of a thermo- structural component of a composite material with a ceramic matrix by producing a coating with the following steps: (A) providing a mixture of colloidal silica, a powder of a silico-aluminous or aluminous refractory ceramic material and water; (B) applying a layer of the mixture on the component; (C) drying this layer; (D) heating the component to a temperature greater than 1000 oC to fire the layer and form a coating of enamel. Independent claims are also included for: (1) the wear resistant coating; (2) a thermo- structural component in a composite material with a ceramic matrix with this wear resistant coating.
