摘要
A nickel-based or cobalt-based superalloy substrate is covered with a protective system which is resistant to thermal, corrosive and erosive attack. An anchoring layer is disposed on the substrate. The anchoring layer is formed as an oxide compound, in particular alumina, doped with nitrogen. A ceramic coating is disposed on the anchoring layer. The modification of the anchoring layer prevents the transmission of diffusing elements through the anchoring layer to the thermal barrier layer.
