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.
Claims18
Feedstock for a cold spray process, comprising:
- a plurality of globule bodies including a plurality of particles bonded to one another and defining therebetween at least one pore,
- wherein the bond is of sufficient strength for the globule to retain both integrity and shape while undergoing acceleration in a cold spray process,
- wherein the plurality of globule bodies are about twenty-five (25) millimeters in size.
Feedstock for a cold spray process, comprising:
- a plurality of globule bodies including a plurality of particles bonded to one another and defining therebetween at least one pore,
- wherein the bond is of sufficient strength for the globule to retain both integrity and shape while undergoing acceleration in a cold spray process,
- wherein each of the plurality of globule bodies include:
- a tip portion and a heel portion opposite the tip portion;
- and
- a surface enveloping the heel and tip portions,
- wherein the surface defines a concavity that extends into the tip portion of the respective globule body to reduce impact strength and expand substrate coverage upon impact of the globule body using a cold spray process.
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;
- and
- shaping the globules, wherein the agglomerating the particulate includes bonding particles of the particulate such that one or more pores are defined within the globules,
- wherein the bond is of sufficient strength for the globule to retain both integrity and shape while undergoing acceleration in a cold spray process,
- wherein each of the plurality of globule bodies include:
- a tip portion and a heel portion opposite the tip portion;
- and
- a surface enveloping the heel and tip portions,
- wherein the surface defines a concavity that extends into the tip portion of the respective globule body to reduce impact strength and expand substrate coverage upon impact of the globule body using a cold spray process.
