Abstract:
A method of metallizing the surface of a substrate electrolessly, by spraying one or more oxidation-reduction solutions thereonto. The steps of this method include: a) physical or chemical treatment to reduce the surface tension of the substrate before metallization; b) electroless metallization of the surface of the substrate treated in step a), by spraying one or more oxidation-reduction solutions in the form of one or more aerosols thereonto; and c) formation of a top coat on the metallized surface. Compact devices for implementing this method and the products obtained are also disclosed.
Abstract:
The subject of the invention is a heat treatment process by flame treatment of at least one thin film deposited on a glass substrate (1) running in the path of at least one flame treatment device comprising at least one burner (2), said treatment being able to increase the degree of crystallization of said at least one thin film and/or to increase the size of the crystallites in said at least one thin film, said process being characterized in that the maximum transient bending “b” is less than 150 mm and respects the following condition: b≦0.9×d where the bending “b” corresponds to the distance, expressed in mm, between the plane of the substrate without heating (P1) and the point of the substrate closest to the plane (P2) passing through the tip (6) of the burner (2) and parallel to the plane of the substrate without heating (P1), “d” corresponds to the distance between the plane of the substrate without heating (P1) and the tip (6) of the burner (2), expressed in mm, the width of the substrate “L” in a direction perpendicular to the run direction (5) being greater than or equal to 1.1 m.
Abstract:
Disclosed is nanocoupling of a polymer onto a surface of a metal substrate for improving coating adhesion of the polymer on the metal substrate, and in vivo stability and durability of the polymer. In accordance with the present invention, the polymers can be grafted via a chemical bonding on the surface of the metal substrate by the nanocoupling, by which adhesion, biocompatibility and durability of a polymer-coated layer which is to be formed later on the metal substrate were remarkably improved; therefore, the nanocoupling according to the present invention can be applied to surface modification of a metal implant, such as stents, mechanical valves, and an articular, a spinal, a dental and an orthopedic implants.
Abstract:
A method of applying a wear-resistant coating comprises mixing about 75% to about 85% by weight chromium carbide and about 15% to about 25% by weight nickel chromium to form a chromium carbide-nickel chromium mixture, and simultaneously heating the chromium carbide-nickel chromium mixture to about 1371 degrees Celsius to about 2204 degrees Celsius and applying the chromium carbide-nickel chromium mixture at a velocity in a range of about 305 meters feet per second to about 915 meters per second by high velocity oxygen fuel (HVOF) spraying.
Abstract:
A polypropylene part of a device for packaging and/or applying a product, including a body having at least one wall covered, at least partly, with at least one finishing coat, the resilience of said polypropylene being greater than or equal to 7 kJ/m2.
Abstract:
A cosmetics applicator includes a material surface (210) and a cosmetic preparation (220) provided on the surface. In one aspect, the cosmetics preparation is retained on the surface at least in part with the assistance of electrostatic attraction between the surface and the cosmetics preparation. In another aspect, a waxy or oily underlay is provided between the surface and the cosmetics preparation, and the material of the surface is selected to facilitate retention of the cosmetics preparation and the underlay while allowing a major proportion of the cosmetics preparation retained thereon to be transferred to a human skin surface in a single wiping pass of the cosmetics preparation across the skin surface.
Abstract:
A method for high temperature resistant bonding of oxygen permeable oxide ceramics of substituted alkaline earth cobaltates by doping assisted diffusive reaction sintering includes providing at least one joining surface of the oxygen permeable ceramics with a Cu-containing additives. At least a join area of the oxygen permeable ceramics is subsequently heated, under loading through forces, to a temperature up to 250 K below a customary sintering temperature of the oxygen-permeable ceramics. The join area is held under the loading at the temperature for 0.5 to 10 hours.
Abstract:
A method of electrostatic spraying of a polymer surface involves oxidation and treating the oxidised surface with a polyamine and an electroconductivity modifying agent which contains a mono-carboxylic acid of from one to 12 carbon atoms.
Abstract:
A method of forming a turbine component that includes a ceramic matrix composite-ceramic insulation composite with a vapor resistant layer is disclosed. The method includes providing an inner tool and an outer tool, wherein the inner and outer tools define a mold for forming a turbine component. A vapor resistant layer can be applied to the inner tool, and a ceramic insulation layer can be applied over the vapor resistant layer in the mold. The vapor resistant layer and the ceramic insulation layer can be partially fired to form a bisque turbine component, and the outer tool can be removed. The inner tool can include a transitory material. A layer of ceramic matrix composite material can be applied to the outside of the bisque turbine component to form a component, and the component can be fired to form a turbine component.
