Abstract
A thermal barrier coating system comprising a metal substrate, a metal bonding layer and a ceramics thermal barrier layer wherein the ceramics thermal barrier layer has a columnar structure of a stabilized zirconia containing a stabilizer or a stabilized ZrO2—HfO2 solid solution containing a stabilizer, and comprises 0.1 to 10 mol % of lanthanum oxide.
