A METHOD OF MANUFACTURING A HOT-GAS COMPONENT WITH A COOLING CHANNEL BY BRAZING A SINTERED SHEET ON A CARRIER ; CORRESPONDING HOT-GAS COMPONENT

摘要

The invention relates to a method of manufacturing a hot-gas component (20) with cooling channels (25) and a hot gas component (20) manufactured by the said method. Pre-sintered preform materials are used for the manufacturing of a hot-gas component (20) with a cooling channel (25). The method initially involves providing a carrier substrate (22) for the hot-gas component (20) and then providing a sheet (24) of pre-sintered preform material. The sheet (24) is then arranged on the carrier substrate (22) so as to form the cooling channel (25). The sheet (24) and the carrier substrate (22) are then brazed to manufacture the hot-gas component (20) with the cooling channel (25).
