    Abstract: We have developed an improved vapor-phase deposition method and apparatus for the application of layers and coatings on various substrates. The method and apparatus are useful in the fabrication of biotechnologically functional devices, Bio-MEMS devices, and in the fabrication of microfluidic devices for biological applications. In one important embodiment, oxide coatings providing hydrophilicity or oxide/polyethylene glycol coatings providing hydrophilicity can be deposited by the present method, over the interior surfaces of small wells in a plastic micro-plate in order to increase the hydrophilicity of these wells. Filling these channels with a precise amount of liquid consistently can be very difficult. This prevents a water-based sample from beading up and creating bubbles, so that well can fill accurately and completely, and alleviates spillage into other wells which causes contamination.

  • Patent number: 7569799
    Abstract: A compound body comprises a steel base element on which is deposited a heater layer. The base element is made of a precipitation hardening steel. In the form of a manifold or material feed tube in a hot duct system, said base element comprises a round or convex surface receiving the heater layer. This heater layer is a compound layer having several strata and/or strata elements which are thick film pastes or sheets and in such form are consecutively deposited, dried and baked-on. The pre-compression generated in this process in the heater layer is increased in controlled manner by precipitation hardening the base element.

  • Publication number: 20090132030
    Abstract: This application relates to a method of modifying the surface of a metal substrate to improve the surface coverage of a coating applied to the substrate. The method comprises heating at least the surface of the substrate to a temperature within the range of approximately 175-400° C.; and applying at least one layer of the coating to the substrate. In one particular embodiment the substrate is heated to a temperature within the range of 200-350° C. The low temperature heating enhances the hydrophilicity of the metal substrate while avoiding the disadvantages of high temperature thermal oxidation.

  • Publication number: 20090074972
    Abstract: An article and method for stabilization of a nickel-based superalloy coated with a diffusion aluminide coating. The region below the aluminide coating is first carburized to form refractory carbides. The article is cleaned and masked as required so that regions that will not have an aluminide coating are not carburized. After placing the article into a furnace and heating in a non-oxidizing atmosphere to a carburizing temperature, a carburizing gas is introduced, and the near surface region is carburized to a depth of about 100 microns. Refractory carbides are formed in this region. When a diffusion aluminide coating is formed on the article, the refractory elements, being present as refractory carbides, are not available to form detrimental TCP phases.
