Abstract
A feedstock for a cold spray process includes a plurality of globule bodies. The globule bodies include a plurality of discrete particles bonded to one another to define porous globule bodies. The bonds between the particles are of sufficient strength such that the globule bodies can retain both the body integrity as well as the body shape when the body experiences acceleration from a conveying gas in a cold spray technique. Methods of making the feedstock and globule bodies are also described.
Claims7
A method making feedstock for a cold spray process, the method comprising:
- receiving particulate;
- agglomerating the particulate into a plurality globules;
- strengthening the globules using heat, wherein strengthening imparts to the globules strength sufficient to retain both integrity and shape while undergoing acceleration in a cold spray process;
- and
- shaping the globules, wherein the agglomerating the globules includes bonding particles of the particulate such that one or more pores are defined within the globules, wherein shaping the globule bodies include shaping the plurality of globule bodies such that the respective globule bodies are about twenty-five (25) millimeters in size.
