Example systems may include an energy source, a material delivery device, and a computing device. The computing device, based on a target height of a layer deposited on a component by directed energy deposition, may control an energy source directed at a component and may control a material delivery device. Controlling the energy source may include advancing an energy beam along a first path to form an advancing molten pool on the component. Controlling the material delivery device may include delivering a material to the advancing molten pool. The material may combine with the advancing molten pool to form a first raised track having an actual height. The layer may include the first raised track. A deposited region of the component may include the layer. The actual height may affect a resultant microstructure within the deposited region.

Directed energy deposition for processing gas turbine engine components

An example spray nozzle distribution pattern testing system may include coaxial collection tubes extending substantially parallel to a major axis, where each coaxial collection tube includes a first end defining an orifice, where the first end is disposed at a first position on a plane substantially orthogonal to the major axis, a second end coupled to an end of a respective outlet tube, and a collection tube wall extending from the first end to the second end, where the collection tube wall at the first end includes a first diameter, where the collection tube wall at a second position between the first end and the second end includes a second diameter greater than the first diameter, where the collection tube wall extending from the second position to the first position tapers toward the major axis at a first angle.

Directed energy deposition spray nozzle distribution pattern testing

A material deposition head may include a body that defines first and second ends, an exterior surface, an interior surface, and one or more material delivery channels, where the exterior surface includes fluting. In some examples, a system may include a fluted material deposition head, a fluidized powder source, and an energy source.
