Abstract
Official abstract text for this publication.
A method for processing a powder material includes feeding a powder material through an additive processing machine to deposit multiple layers of the powder material onto one another and using an energy beam to thermally fuse selected portions of the layers to one another with reference to data relating to a particular cross-section of an article being formed. The powder material has spherical metal particles and a spaced-apart distribution of ceramic nanoparticles attached to the surfaces of the particles. The ceramic nanoparticles form a dispersion of reinforcement through the formed article.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for processing a powder material, the method comprising: feeding a powder material through an additive processing machine to deposit multiple layers of the powder material onto one another, the powder material having spherical metal particles and a spaced-apart distribution of ceramic nanoparticles attached to the surfaces of the particles; and using an energy beam to thermally fuse selected portions of the layers to one another with reference to data relating to a particular cross-section of an article being formed, the ceramic nanoparticles forming a dispersion of reinforcement through the formed article. 2. The method as recited in claim 1 , wherein the ceramic nanoparticles are selected from the group consisting of oxides, nitrides, carbides, and combinations thereof. 3. The method as recited in claim 1 , wherein the ceramic nanoparticles are oxide nanoparticles. 4. The method as recited in claim 1 , wherein the ceramic nanoparticles are zirconium oxide nanoparticles. 5. The method as recited in claim 1 , wherein the powder material has a composition, by weight, of 0.1-5% of the ceramic nanoparticles. 6. The method as recited in claim 1 , wherein the spherical metal particles are selected from the group consisting of nickel, chromium, aluminum, titanium, iron, and combinations thereof. 7. The method as recited in claim 1 , wherein the spherical metal particles are nickel-based particles and include chromium. 8. The method as recited in claim 1 , wherein the ceramic nanoparticles are zirconium oxide nanoparticles and the powder material has a composition, by weight, of 0.1-5% of the ceramic nanoparticles. 9. The method as recited in claim 8 , wherein the spherical metal particles are selected from the group consisting of nickel, chromium, aluminum, titanium, iron, and combinations thereof. 10. The method as recited in claim 8 , wherein the spherical metal particles are nickel-based particles and include chromium.
