Currently operating new generation aircraft engines are equipped with multi-hole combustion chambers, coated with a thick ZrO2-4 mol% Y2O3 (YpSZ) thermal barrier coating (TBC). The local repair of such multi-hole combustors requires the development o

Thermal barrier coatings (TBC) in service are prone to the attack by molten calcium–magnesium aluminosilicates (CMAS) resulting from the ingestion of siliceous minerals (dust, sand, volcanic ash) by the aeroengines. As CMAS deposits observed on ex-

The use of thermal barrier coatings (TBCs) on turbine blades and vanes located in the hot sections of gas turbine engines has allowed higher engine operating temperatures leading to temperatures of the order of 1200 °C at the surface of the ceramic

C/C composite oxidation model

Autor: Y Renollet, O. Lavigne, J.-M. Dorvaux, Marie-Pierre Bacos

Publikováno v: Carbon. 38:105-117

A model of the oxidation behaviour of C/C composites was developed. The purpose of the model is to predict the carbon loss that occurs at the outer surface and within the porosity of the composite. It takes into account the transport of species in th
