摘要： The invention relates to a heat-insulating layer system for metallic components, especially for components of a gas turbine such as an aircraft engine. Said heat-insulating layer system (13) comprises an inner contact layer (14) and an outer covering layer (15), the inner contact layer (14) being applied to a surface (11) of a gas turbine component (10) with a coupling layer (12) arranged in-between. According to the invention, the inner contact layer (14) is formed from a zirconium oxide which is partially stabilised by yttrium or yttrium oxide, and the outer covering layer (15) is formed from lanthane hexaaluminate.
