Combined heat insulating layer systems

摘要

The invention discloses a component with a heat-insulating layer on its surface. The heat-insulating layer comprises a lower region and an upper region. The lower region is situated between the component and the upper region. The lower region consists entirely or predominantly of YSZ or a glass-metal composite material. The upper region consists entirely or predominantly of a material which provides a stable phase at temperatures significantly above 1200° C. The component can be used at temperatures significantly above 1200° C.
