  • Publication number: 20020022135
    Abstract: A process for producing a coating on a refractory structural member, in which a noble metal alloy is applied as a coating material to the refractory structural member. The noble metal alloy contains, among other constituents, an oxidizable substance, which includes boron and/or phosphorus and/or antimony and/or arsenic. The refractory structural member and the coating are heated at least once in an oxygen-containing atmosphere to a temperature T that is greater than or equal to the liquidus temperature TL of the noble metal alloy The oxidizable substance is oxidized during this heating process, and the oxide that has formed is at least partially vaporized. The temperature T is maintained until the proportion of oxidizable substance in the coating is <0.1 atomic percent, and the coated refractory structural member is then cooled.

  • Patent number: 6337109
    Abstract: A method of producing a crystalline silicon film having superior crystalline properties is characterized by a method of adding catalytic metal for accelerating crystallization of the amorphous silicon film. The catalytic element is adsorbed on the surface of the amorphous silicon film by using a vapor or a gas, so that a low temperature short time crystallization is made possible by using the catalytic metal at heat crystallization. Especially, by controlling partial pressures, when adsorption state is made into monomolecular layer adsorption with covering rate 1, superior uniform crystalline silicon film can be obtained.

  • Patent number: 6284317
    Abstract: The present invention relates to methods of derivatizing semiconductor surfaces, particularly porous silicon surfaces with silicon-carbon units. The derivatization occurs through the direct addition of an organometallic reagent in the absence of an external energy source such as heat and photo- or electrochemical energies. The method of the invention allows the formation of unique intermediates including silicon hydride units bonded to metal ions. Because of these unique intermediates, it is possible to form previously inaccessible silicon-carbon units, for example where the carbon atom is an unsaturated carbon atom. Such inaccessible silicon-carbon units also include silicon-polymer covalent bond formation, in particular where the polymer is a conducting polymer. Thus, the present invention also provides a novel semiconductor surface/polymer junction having improved interfacial interactions.

  • Publication number: 20010007699
    Abstract: Disclosed is a method of coating a catalyst to a support for use in acrolein oxidation reaction. Metallic salt components of the catalyst including molybdate, vanadate and tungstate are dissolved in a liquid to form a suspension of particles of the catalyst. The precipitation of the catalyst particles is controlled by homogenizing the catalyst particles suspended in the liquid. The phase separation between the catalyst particles and the liquid can be substantially slowed down by the homogenization. Then the catalyst is coated on an inert support by applying the suspension of the catalyst particles to the support. In the suspension, the total weight of water is about 0.8 to about 5 times of the total weight of the metallic salts in the catalyst. This method of preparing suspension minimizes the amount of the liquid required to dissolve the metallic salts, which reduces the amount of time and energy to be used in evaporating the liquid from the suspension.

  • Patent number: 6251474
    Abstract: Substantially spherical magneto-plumbite ferrite (barium or strontium ferrite) particles are formed from well-dispersed ultra-fine substantially spherical iron-based oxide and/or hydroxide particles as precursor particles. The precursor particles are mixed with a colloidal barium or strontium carbonate (BaCO3 or SrCO3), and with small amounts of a byproduct, such as sodium or potassium chloride (NaCl or KCl) or hydroxide (NaOH or KOH) or nitrate (NaNO3 or KNO3), functioning as a flux to lower the calcination temperature. The particles are filtered out of the mixture, dried, and calcined for a time sufficiently long and/or at a temperature sufficiently high to form magneto-plumbite ferrite from the precursor particles, and for a time sufficiently short and/or a temperature sufficiently low to maintain the general spherical shape of the precursor particles.

In one embodiment, a method for a gas turbine engine includes a directionally solidified metallic substrate, e.g., a superalloy, which defines an airfoil, a root and a platform located between the blade and root. The platform has an underside adjacent the root, and a corrosion resistant overlay coating such as an MCrAlY or a noble metal containing aluminide or corrosion inhibiting ceramic is located on portions or the blade not previously covered with such coatings, e.g., the underside of the platform and the neck. The applied coating prevents corrosion and stress corrosion cracking of blade in these regions. Where the airfoil is also coated, the airfoil coating may have a composition different from that of the coating on the underplatform surfaces.
