  • System and method for light assisted friction stir processing and welding of metallic and non-metallic materials
    Patent number: 10647064
    Abstract: An apparatus for use in a friction stir operation, such as friction stir welding (FSW) or friction stir processing (FSP). The apparatus may have a rotating tool adapted to be plunged into a material, where the material is susceptible to being softened by heating. The rotating tool may further be adapted to be advanced along a surface of the material. An optical energy generating subsystem may be used to heat a portion of the material using optical energy as the tool is advanced along the material.
    Type: Grant
    Filed: October 16, 2012
    Date of Patent: May 12, 2020
    Assignee: Lawrence Livermore National Security, LLC

  • Surface modification of synthetic diamond for producing adherent thick and thin film metallizations for electronic packaging
    Patent number: 5853888
    Abstract: An article and a method of making surface modified synthetic diamond substes at temperatures below 500.degree. C. for electronic packaging applications are described. The article consists of a synthetic diamond substrate, the surface of which has been modified by providing an adherent thin coating of a ceramic (alumina) material so as to enable metallization of synthetic diamond by current industrial methods. The method of surface modification comprises deposition of a thin transition metal layer on the synthetic diamond substrate prior to low temperature reactive vapor deposition of aluminum followed by annealing in an oxygen atmosphere.
