Embodiment Construction

[0031] The following description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the invention is defined by the appended claims.

[0032] Reference throughout the specification to "one embodiment," or "an embodiment," means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, the appearances of the phrase "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0033] In the following exemplary description, it must be assumed that all compone...

Abstract

The method of manufacturing a component (40) of a turbomachine by powder metal hot isostatic pressing uses a container (41) defining outside surfaces (42A, 42B, 42C, 42D, 42E, 42F, 42G, 42H) of the component (40); a metal insert (443) is located inside the container (41) before filling the container (41) with metal powder; the insert (443) is left in the component (40) after the end of its manufacturing. Advantageously, a metal core (44) is located inside the container (41) before filling the container (41) with metal powder, the core (44) is removed from the component (40) before the end of its manufacturing. In this way, net shape surfaces may be obtained without manufacturing trials.

Description

technical field [0001] Embodiments of the subject matter disclosed herein relate to methods of manufacturing turbomachine components, turbomachine components, and turbomachines. Background technique [0002] One technique used for the manufacture of turbomachinery components is powder metallurgy hotisostatic pressing (P / M-HIP for short); this technique is used, for example, to manufacture hermetic seals for centrifugal compressors made of metallic materials impeller. [0003] One reason this technique is attractive is that, through certain approaches, it allows the manufacture of metal parts that require no further machining or require a limited amount of machining of the entire part or at least some surfaces of the part; in this case Hereinafter, the technique is referred to as "Net Shape HIP" and although this approach can be applied to both the exterior and interior surfaces of a part, it is especially useful when applied to interior surfaces when machining of these surf...
