Abstract

Additive manufacturing techniques may be utilized to construct effusion plates. Such additive manufacturing techniques may include defining a configuration for an effusion plate having one or more internal cooling channels. The manufacturing techniques may further include depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a cross-sectional shape corresponding to the defined configuration. Such methods may be implemented to construct an effusion plate having one or more channels with a curved cross-sectional geometry.

Hybrid additive manufacturing methods using hybrid additively manufactured features for hybrid components

Patent Lacy, Benjamin Paul; Kottilingam, Srikanth Chandrudu; Schick, David Edward

A hybrid additive manufacturing method comprises building an additive structure on a pre-sintered preform base, wherein building the additive structure comprises iteratively fusing together a plurality of layers of additive material with at least a first layer of additive material joined to the pre-sintered preform base, and wherein the pre-sintered preform base comprises an initial shape. The hybrid additive manufacturing method further comprises modifying the initial shape of the pre-sintered preform base comprising the additive structure into a modified shape comprising the additive structure, and, joining the pre-sintered preform base in its modified shape to a component.

Additive manufacturing method for SRF components of various geometries

Patent Rimmer, Robert; Frigola, Pedro E; Murokh, Alex Y

An additive manufacturing method for forming nearly monolithic SRF niobium cavities and end group components of arbitrary shape with features such as optimized wall thickness and integral stiffeners, greatly reducing the cost and technical variability of conventional cavity construction. The additive manufacturing method for forming an SRF cavity, includes atomizing niobium to form a niobium powder, feeding the niobium powder into an electron beam melter under a vacuum, melting the niobium powder under a vacuum in the electron beam melter to form an SRF cavity; and polishing the inside surface of the SRF cavity.
