Publication number: 20210008619Abstract: Embodiments described herein relate generally to systems and methods for using nanocrystalline metal alloy particles or powders to create nanocrystalline and/or microcrystalline metal alloy articles using additive manufacturing. In some embodiments, a manufacturing method for creating articles includes disposing a plurality of nanocrystalline particles and selectively binding the particles together to form the article. In some embodiments, the nanocrystalline particles can be sintered to bind the particles together. In some embodiments, the plurality of nanocrystalline particles can be disposed on a substrate and sintered to form the article. The substrate can be a base or a prior layer of bound particles. In some embodiments, the nanocrystalline particles can be selectively bound together (e.g., sintered) at substantially the same time as they are disposed on the substrate.Type: ApplicationFiled: February 12, 2020Publication date: January 14, 2021Applicant: Veloxint CorporationInventors: Alan C.

Patent number: 10590514Abstract: Techniques for forming an enclosure comprised of aluminum zirconium alloy layer are disclosed. In some embodiments, aluminum ions and zirconium ions can be dissolved in a non-aqueous ionic liquid in an electrolytic plating bath. A reverse pulsed electric current can facilitate in co-depositing the aluminum ions and the zirconium ions onto a metal substrate. The resulting aluminum zirconium alloy layer can include nanocrystalline grain structures, which can impart the alloy layer with increased hardness and increased resistance to scratching, denting, and abrasion. In some embodiments, the aluminum zirconium alloy layer can be anodized to form an aluminum oxide layer. Subsequent to the anodization operation, the oxidized layer is able to retain its substantially neutral color.Type: GrantFiled: April 7, 2017Date of Patent: March 17, 2020Assignee: XTALIC CORPORATIONInventors: Evgeniya Freydina, Joshua Garth Abbott, Alan C. Lund, Robert Daniel Hilty, Shiyun Ruan, Jason Reese, Lisa J. Chan, James A. Wright, James A. Curran

Patent number: 10590558Abstract: Techniques for forming an enclosure comprised of an aluminum alloy are disclosed. In some embodiments, aluminum ions and metal element ions can be dissolved in a non-aqueous ionic liquid in an electrolytic plating bath. A reverse pulsed electric current can facilitate in co-depositing the aluminum ions and the metal element ions onto a metal substrate. The resulting aluminum alloy layer can include nanocrystalline structures, which can impart the alloy layer with increased hardness and increased resistance to scratching, corrosion, and abrasion. In some embodiments, the metal element ion is chromium and the aluminum alloy layer includes a chromium oxide passivation layer formed via a passivation process. Subsequent to the passivation process, the formation of the chromium oxide layer does not impart a change in color to the aluminum alloy layer. In some embodiments, hafnium ions are co-deposited with aluminum ions to form an aluminum hafnium alloy.Type: GrantFiled: April 7, 2017Date of Patent: March 17, 2020Assignee: XTALIC CORPORATIONInventors: Evgeniya Freydina, Joshua Garth Abbott, Alan C.

Patent number: 9758888Abstract: Metal surface pretreatments using ionic liquids prior to electroplating are disclosed. The surface treatments include forming an activated metal substrate surface by removing any naturally formed metal oxide layers formed on the surfaces of the metal substrates. According to some embodiments, the surface treatments include exposing the metal substrate to a non-aqueous ionic liquid. In some embodiments, an electrical current is applied to the metal substrate to assist removal of the metal oxide layer. The electrical current can be a pulsed anodic current. After activating the surface, a metal layer can be deposited on the activated surface. In some embodiments, the metal layer is electrodeposited in the same ionic liquid used to form the activated surface. The resultant metal coating is resistant to scratching and peeling.Type: GrantFiled: May 6, 2014Date of Patent: September 12, 2017Assignee: Apple Inc.Inventors: Evgeniya Freydina, Shiyun Ruan, Christopher A.
