The invention relates to a method for the protective treatment of wood, derived timber products and wood-type substrates by means of thermal treatment at 60-250null C. and additional treatment using an amine and/or amine derivative of general formula (Ia), (Ib) or (Ic) wherein R1 and R4 independently represent C6-24 alkyl; R2 and R3 independently represent C1-24 alkyl or (CH2)nullNH2; R5, R6, R8 and R9 independently represent C1-24 Alkyl; R7 represents C6-24 alkyl or benzyl; R10 independently represents C1-24 alkyl or nullnull(CH2)2nullOnullnR11 where nnull1-20; R11 represents hydrogen or optionally substituted phenyl; and Xnull represents a monovalent inorganic or organic anion or an equivalent of a polyvalent inorganic or organic anion. The additional treatment can also be carried out using a corresponding salt the wood treated according to said method has good resistance even to harmful organisms which cannot be reliably controlled by means of only a heat treatment. The inventive method is carried out without compounds containing heavy metals and the wood treated in this way has no impact on the environmental either during the use or during the disposal thereof.

Abstract:
A metallic alloy made of metallic constituent elements is fabricated and utilized by first furnishing a mixture of nonmetallic precursor compounds of the metallic constituent elements, and thereafter chemically reducing the mixture of nonmetallic precursor compounds to produce a metallic alloy as a metallic alloy powder, without melting the metallic alloy. The metallic alloy powder is applied to a surface of a substrate article, preferably in a coating, joining, or deposition application.
Abstract:
A method for applying a bond coat on a metal-based substrate is described. A slurry which contains braze material and a volatile component is deposited on the substrate. The slurry can also include bond coat material. Alternatively, the bond coat material can be applied afterward, in solid form or in the form of a second slurry. The slurry and bond coat are then dried and fused to the substrate. A repair technique using this slurry is also described, along with related compositions and articles.
Abstract:
A method of preparing a coated solid dosage form is disclosed wherein a solid dosage form, such as a compressed tablet with active agent dispersed therein, is coated at least twice with a coating solution comprising a water-insoluble coating polymer and a water-soluble pore former, and cured after at least the first coating step. The method of the present invention allows for the production of cured coated solid dosage forms using very short curing times. Coated solid dosage forms produced according to the present invention have been found to have long extended release characteristics.
Abstract:
The present invention relates to a coating composition for coating various substrates, particularly automotive bodies. A crosslinkable component of the composition includes an acid functional acrylic copolymer polymerized from a monomer mixture comprising 2 percent to 12 percent of one or more carboxylic acid group containing monomers, percentages based on total weight of the acid functional acrylic copolymer, and 0.2 percent to 2 percent of amorphous silica, percentages based on total weight of the crosslinkable component. The crosslinking component can includes polyisocyanates, melamines, or a combination thereof.

A method for manufacturing a capacitor on a single-crystal silicon substrate, comprising the steps of: forming a silicon oxide layer; depositing and completely oxidizing a titanium layer; depositing a platinum layer of a thickness ranging between 800 and 1200 null, intended to form a first electrode of the capacitor, the platinum deposition being performed by sputtering at a pressure of 1.5null105 Pa and at a temperature ranging between 360 and 600null C.; performing an anneal under an oxidizing atmosphere at a temperature ranging between 650 and 800null C.; depositing and oxidizing a thin layer of a ferroelectric material, intended to form the inter-electrode insulator of the capacitor; and depositing a conductive layer, intended to form a second electrode of the capacitor.
Abstract:
A low cost chromide and chromide/aluminide process for moderate temperature applications. A gas turbine engine component is cleaned and coated with a layer of metal, generally chromium or chromium and aluminum, containing paint. The metal containing paint layer is heated to a first temperature for a first period of time in an air environment to volatilize the solvents in the paint. The metal containing paint layer is heated to a second temperature for a second period of time in an oxygen-free atmosphere to volatilize the solvents in the paint. The now metal layer and component are heated to a third temperature for a third period of time to interdiffuse the metal and the metal of the component. The component and diffusion layer are then cooled to ambient temperature.

Abstract:
A method for applying a coating system that is applied to a surface of a component, such as a turbine nozzle, for preventing or at least substantially preventing interdiffusion between the component surface and a protective thermal layer applied to the component surface when the thermal layer is exposed to elevated temperatures. The method includes applying a carrier layer containing aluminum to the component surface. Next, the layer is heated to a first predetermined temperature for a first predetermined period of time in the substantial absence of oxygen to bond the aluminum with the component surface, the heat dissolving the carrier portion of the aluminum layer. The remaining portion of the aluminum layer is then heated to a second predetermined temperature for a second predetermined period of time to form an oxidized aluminum layer. Finally, at least one protective thermal layer is applied over the oxidized aluminum layer.
Abstract:
A surface of an article is protected by coating the surface with a silicon-containing coating by preparing a coating mixture of silicon, a halide activator, and an oxide powder, positioning the surface of the article in gaseous communication with the coating mixture, and heating the surface of the article and the coating mixture to a coating temperature of from about 1150null F. to about 1500null F. The article is preferably a component of a gas turbine engine made of a nickel-base superalloy.
