Abstract
Official abstract text for this publication.
Methods for large-scale additive manufacturing of high-strength boron nitride nanotubes (BNNT)/aluminum (Al) (e.g., reinforced Al alloy) metal matrix composites (MMCs) (BNNT/Al MMCs), as well as the BNNT/Al MMCs produced by the large-scale additive manufacturing methods, are provided. A combination of ultrasonication and spray drying techniques can produce good BNNT/Al alloy feedstock powders, which can be used in a cold spraying process.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for fabricating a boron nitride nanotubes (BNNT)/aluminum (Al) metal matrix composite (MMC), the method comprising: preparing a BNNT-Al powder in which BNNTs are dispersed in a first powder comprising Al; and performing a cold spraying process with the BNNT-Al powder as a feedstock to fabricate the BNNT/Al MMC, the preparing of the BNNT-Al powder comprising dispersing BNNTs in isopropyl alcohol (IPA) to give a BNNT-IPA solution free of Al, adding the first powder comprising Al to the BNNT-IPA solution to give a first mixture, performing tip sonication on the first mixture to give an intermediate mixture, and performing a drying process on the intermediate mixture to give the BNNT-Al powder. 2. The method according to claim 1 , the BNNTs being uniformly dispersed in the first powder. 3. The method according to claim 1 , the first powder being an Al alloy powder. 4. The method according to claim 1 , the first powder having a particle size of 5 micrometers (μm) or less. 5. The method according to claim 1 , the first powder having a particle size in a range of from 20 μm to 50 μm. 6. The method according to claim 1 , the performing of the cold spray process comprising using a handheld cold spray gun. 7. The method according to claim 1 , the performing of the cold spray process comprising using a cold spray gun that is attached to a robotic arm to three-dimensional (3D) print the BNNT/Al MMC. 8. The method according to claim 7 , the robotic arm being configured to move along or rotate about a number of axes, the number of axes being at least three. 9. The method according to claim 8 , the number of axes being at least six. 10. The method according to claim 1 , the cold spraying process being performed such that a temperature of the BNNT-Al powder and a temperature of the BNNT/Al MMC does not exceed 400° C.
