PRODUCT, ESPECIALLY A GAS TURBINE COMPONENT, WITH A CERAMIC HEAT INSULATING LAYER

摘要

The invention relates to a product (3), especially a component of a heat engine such as a gas turbine, which can be exposed to a hot aggressive gas (7). The product (3) has a metal base body (1) to which a ceramic heat insulating layer (4) is applied. The heat insulating layer (4) consists of a metal mixed oxide system and a lanthanum aluminate and/or calcium zirconate, whereby the calcium is replaced by a substitute element, especially strontium.
