Thermal insulating layer for a metallic component and its process of manufacture

摘要

A process for the manufacture of a thermo-mechanically stable thermal insulating layer, in which a ceramic thermal insulating layer is applied to a metallic component by thermal spraying and the thermal insulating layer is shot peened during and/or after its application in order to reduce sintering effects. The ceramic thermal insulating layer has a porous structure which is opened up by the formation of microscopic fissures formed near the surface of the layer by the shot peening.
