  • Publication number: 20150351445
    Abstract: An anti-microbial coated device includes a device sized and configured for use in a microbe-contaminating environment. The device includes a substrate having a surface configured to be exposed in the microbe contaminating environment. A cold-sprayed anti-microbial coating is deposited on at least a portion of the surface of the substrate. The anti-microbial coating includes fused metal particles and having a thickness in a range from 100 nm to 1 mm.
    Type: Application

  • Patent number: 7209546
    Abstract: An apparatus and method for applying an absorptive coating to a portion of the evacuated enclosure in an x-ray generating device is disclosed. The absorptive coating is applied to the inner surface of the evacuated enclosure to enhance its heat dissipation characteristics, which in turn assists in tube cooling during x-ray production. The absorptive coating is applied atop an intermediate bonding layer. Both the absorptive coating and the intermediate bonding layer are applied to the evacuated enclosure surface by electroplating processes. A plating apparatus comprising the evacuated enclosure portion, a plating fixture, and a base plate is used both to contain the electroplating solution during the plating process, as well as to facilitate its entry into and removal from the evacuated enclosure. A method of employing the plating apparatus to apply the intermediate bonding layer and the absorptive coating is also disclosed.
