Abstract
A system comprising a substrate and a ceramic thermal barrier layer formed of columns which is applied to the substrate, characterized in that the columns are spatially separated from each other at the substrate or at least hardly contact each other is disclosed. A method for producing the system by laser welding is also disclosed. The disclosed material makes it possible to produce durable, heat-resistant components that can be used, for example, in turbines or in metal-supported fuel cells.
Claims17
A system comprising a substrate and a ceramic thermal barrier layer formed of first columns applied directly to an upper surface of the substrate, wherein each first column comprises a ceramic material, wherein each first column comprises a first portion of the ceramic material adjacent to the substrate which does not contain any cavities produced in the ceramic material and a second portion of the ceramic material spaced apart from the substrate that includes at least one cavity produced in the ceramic material, wherein the first columns are spatially separated from each other at the upper surface of the substrate by a gap having a distance of at least 5 μm, wherein the ceramic material is non-porous.
