Method and apparatus for the production and repair of thermal barrier

2014 
A heat insulating tile (34) with a hard solder layer (46) is sintered together with a ceramic layer (48) is applied to a substrate (26) of a component for the manufacture or repair of a thermal barrier coating (28), (for example on a gas turbine ring segment 22, 24) brazed. The tile can be produced by a first layer of a metallic brazing material is deposited in a mold housing (40); a second layer is deposited from a ceramic powder on the metallic brazing material and the two layers are sintered together by means of spark plasma sintering, whereby the sintered together ceramic / metal tile is formed. A material property of an existing, to be repaired thermal barrier coating can be determined (90), and the sintering can be controlled corresponding to the property (93) such that tiles are generated which are compatible with respect to a material property such as thermal conductivity with the existing thermal barrier coating.
