Claims9
An article of manufacture comprising:
- a metaillic substrate:
- a thermal barrier coating disposed on the metallic substrate;
- wherein the thermal barrier coating comprises a spinel material and an oxide material admixed to the spinel material, the oxide material selected from the group of MgO, HfO2, NiO, CoO, and Cr2O3.
An article of manufacture comprising:
- a metallic substrate;
- a thermal barrier coating disposed an the metallic substrate;
- wherein the thermal barrier coating comprises a spinel material selected from the group of CoMg2O4, CoFe2O4, CoCr2O4, CoTi2O4, CoAl2O4, NiMg2O4, NiTi2O4, TiMg2O4, TiFe2O4, TiCr2O4, and TiAl2O4.
An article of manufacture comprising:
- a metallic substrate;
- a thermal barrier coating disposed on the metallic substrate;
- wherein a first portion of the thermal barrier coating comprises a normal spinel material and a second portion of the thermal barrier coating comprises an inverse spinel material.
