METHOD OF MANUFACTURING A HOT-GAS COMPONENT WITH A COOLING CHANNEL AND A HOT-GAS COMPONENT THEREOF

摘要

A method of manufacturing a hot-gas component with cooling channels and a hot gas component manufactured by the method is provided. Pre-sintered preform materials are used for the manufacturing of a hot-gas component with a cooling channel. The method initially involves providing a carrier substrate for the hot-gas component and then providing a sheet of pre-sintered preform material. The sheet is then arranged on the carrier substrate so as to form the cooling channel. The sheet and the carrier substrate are then brazed to manufacture the hot-gas component with the cooling channel.
