Abstract:
1. A method of manufacturing a thermal barrier coating product comprising a metal substrate, a metal bonding layer, and a ceramic thermal barrier layer formed integrally on the surface of the metal substrate via the metal bonding layer, the method comprising: forming the metal bonding layer on the surface of the metal substrate; melting a composite oxide deposition material by an electron beam physical vapor deposition method to yield a resulting raw material vapor, wherein the composite oxide deposition material comprises 2 to 10 mol % of lanthanum oxide and is obtained by adding La depositing the resulting raw material vapor on the surface of the metal bonding layer to form the ceramic thermal barrier layer having a columnar structure of a zirconia-hafnia solid solution containing the stabilizer, wherein the ZrO the ceramic thermal barrier layer is represented by the general formula: (Zr where M
