  • Method for enhancing bond strength through in-situ peening
    Patent number: 9938624
    Abstract: One embodiment includes a method for enhancing bond strength between a powder deposit and a substrate. Powder is deposited on the substrate. Powder is shot peened with peening media that is harder than both the powder and the substrate to produce bond strength between the powder and the substrate that is at least twice bond strength between the powder and the substrate without shot peening.
    Type: Grant
    Filed: October 17, 2014
    Date of Patent: April 10, 2018
    Assignee: United Technologies Corporation

  • Article having composite coating
    Patent number: 9719174
    Abstract: A composite article includes a substrate and a powder-derived composite coating on the substrate. The composite coating includes discrete regions of a first material and discrete regions of a second material. At least one of the first material or the second material is a chemical precursor.

  • ADDITIVE MANUFACTURED ENHANCED SHEET BEND AND METHOD OF MANUFACTURE
    Publication number: 20150352618
    Abstract: A folded sheet assembly and method of manufacture includes a sheet having an un-folded state with a pre-determined bend-line. The sheet may be weakened along the bend-line to facilitate precise bending of the sheet and into a folded state. A segment of the assembly is additively manufactured to the bend for reinforcement. Weakening of the sheet along the bend-line may be achieved by placement of perforations through the sheet when in the unfolded state. The perforations may be filled by the segment when the sheet is in the folded state.

  • COMPOSITE ARTICLE HAVING SILICATE BARRIER LAYER AND METHOD THEREFOR
    Publication number: 20120308836
    Abstract: A method of processing a composite article includes controlling a preheat temperature of a workpiece to be less than 700° C./1292° F. The workpiece includes a substrate and a bond coat that is disposed on the substrate. With the workpiece at the preheat temperature, deposition of a barrier layer onto the bond coat is commenced. The barrier layer includes a rare earth silicate material having a rare earth element selected from lanthanide series elements, yttrium, scandium and combinations thereof.
