METAL-CERAMIC GRADED-INDEX MATERIAL, PRODUCT PRODUCED FROM SAID MATERIAL, AND METHOD FOR PRODUCING THE MATERIAL

摘要

A metal-ceramic gradient material, in particular for a thermal shield or a gas turbine blade, includes a metal base material, a ceramic and an additive for high-temperature oxidation protection. The metal base material has a concentration decreasing from a metal-rich zone into a ceramic-rich zone. The additive has a concentration with a concentration gradient. The concentration of the additive has a maximum. A product made from a metal-ceramic gradient material and a process for producing a metal-ceramic gradient material are also provided.
