Multi-layer material for gas turbine vanes and heat shields, has a metallic bonding layer between the substrate and an inner ceramic layer supporting an outer ceramic layer

摘要

The multi-layer material (1), especially for the vanes or heat shields of gas turbines, has a substrate (4) to support a metallic bonding layer (7), an inner ceramic layer (10) and an outer ceramic layer (13) containing Gd 2Zr 2O 7 at a rate of at least 80 wt.% and especially 100 wt.%.
