Embodiment Construction
[0024]Further advantages, characteristics and features of the present invention will become clear in the description of an exemplary embodiment detailed hereinbelow.
[0025]FIG. 1 shows a purely schematic illustration of an apparatus 1 which can be used for producing turbine blades by the method according to the invention. The apparatus 1 has a housing 2, which surrounds two spaces or chambers 3 and 4 that are partitioned off by a partition wall (not shown in more detail) having a through-opening 15 in the housing 2. The powder production is effected in one space 4, while the component 27 is sintered in the other space 3.
[0026]The spaces 3 and 4 each have a vacuum pump 5 and 6, such that the spaces 3 and 4 can be pumped out separately from one another. Alternatively, however, provision can be made to provide merely a single pump for pumping out the entire interior of the housing 2.
[0027]In addition, provision is made of a plurality of gas feeds 7, 8, 9, which in turn make it possible ...
