Thermal barrier coating system

摘要

In a laminated thermal insulation system consisting of a substrate supporting other layer(s), (a) the mechanical properties of at least one layer (25, 28) based on matrix material (31) are improved by the presence of a second phase (34) in the matrix material, (b) one layer (28) is of ceramic and (c) the second phase is only locally present in the ceramic layer. An independent claim is included for the production of a laminated thermal insulation system, by (i) applying a layer of ceramic matrix material (31) onto a substrate (or onto another layer) by a coating procedure (specifically by plasma spraying, physical vapor deposition (PVD) or chemical vapor deposition (CVD) methods) and (ii) incorporating the second phase material (34) into the ceramic matrix via an auxiliary nozzle.
