Abstract (en)

[origin: WO9853940A1] The invention relates to a metal-ceramic graded-index material, especially for a heat shield or a gas turbine blade, comprising a metallic base material, a ceramic and an additive to provide resistance to oxidation at high temperatures. The concentration of the metallic base material decreases from an area with a high metal content to an area with a high ceramic content. The concentration of the additive has a concentration gradient.
