  • LASER WELDABLE STERLING ALLOY
    Publication number: 20230019816
    Abstract: A sterling silver chain and method of manufacturing a sterling silver chain comprising a plurality of chain links. Each of the chain links can comprise a sterling silver wire, the sterling silver wire comprising a first end and a second end. Each of the first end and the second end of each of the plurality of chain links can be joined together through a weld. Each of the plurality of chain links can comprise at least 92.5% by weight silver and at least 6.5% by weight tin.

  • Cobalt, iron, boron, and/or nickel alloy-containing articles and methods for making same
    Patent number: 11101118
    Abstract: Methods for making a high purity (>99.99%) and low oxygen (<40 ppm) sputtering target containing Co, CoFe, CoNi, CoMn, CoFeX (X=B, C, Al), Fe, FeNi, or Ni alloys with a column microstructure framed by boron intermetallics are disclosed. The sputtering target is made by directional casting a molten mixture of the metal alloy, annealing to remove residual stresses, slicing, and optional annealing and finishing to obtain the sputtering target.

    Assignee: Materion Corporation
    Inventors: Xingbo Yang, Dejan Stojakovic, Matthew J. Komertz, Arthur V. Testanero
  • Methods for surface preparation of sputtering target
    Patent number: 10604836
    Abstract: Methods for finishing a sputtering target to reduce particulation and to reduce burn-in time are disclosed. The surface of the unfinished sputtering target is blasted with beads to remove machining-induced defects. Additional post-processing steps include dust blowing-off, surface wiping, dry ice blasting, removing moisture using hot air gun, and annealing, resulting in a homogeneous, ultra-clean, residual-stress-free, hydrocarbon chemicals-free surface.
