Abstract
Method for producing or repairing cooling channels (7a) of a gas turbine component (1), whereby the cooling channels (7a) are masked with a thermally stable filling material (3) on the cast gas turbine component (1), and another epitactic layer (6) is created above the ceramic material (3) with the help of a laser (4) and a powder (5). The thermally stable filling material (3) is removed by etching.
