Abstract:
The invention relates to a method for doping and/or coloring glass. In the method a two- or three-dimensional layer is formed on the surface of the glass, and the layer is further allowed to diffuse and/or dissolve into the glass to change the transmission, absorption, reflection and/or scattering of the electromagnetic radiation of the glass. The layer of nanomaterial comprises at least one component that causes the above-mentioned change and at least one component that lowers the melting point of the above-mentioned component causing the change.
Abstract:
The present invention relates to a powder thermal spray composition having a thermoset material and a thermoplastic material. The thermal spray compositions may also include phosphorescent materials to allow the substrate to glow in the dark when applied and/or anti-microbial materials to retard microbial growth on surfaces to which it is applied. The present invention also relates to zinc plastic thermal spray compositions used to coat surfaces, such as steel, to more effectively bond thermal spray compositions and to prevent corrosion of the steel.
Abstract:
A process for the in-flight surface treatment of powders using a Dielectric Barrier Discharge Torch operating at atmospheric pressures or soft vacuum conditions is described herein. The process comprising feeding a powder material into the Dielectric Barrier Discharge Torch yielding powder particles exhibiting a reduced powder agglomeration feature; in-flight modifying the surface properties of the particles; and collecting coated powder particles. An apparatus for surface treating micro- and nanoparticles comprising a Dielectric Barrier Discharge Torch operating at atmospheric pressure or soft vacuum conditions is also described herein.

Abstract:
A thermal spray coating composition comprising up to about 90 weight percent of the composition of a first thermoplastic material and up to about 50 weight percent of the composition of at least one additional thermoplastic material that is different from the first thermoplastic material is disclosed. Additional components can be added to the empirical compositions in order to best additional secondary properties.
Abstract:
A method and apparatus for spray coating a substrate with non-melting polymers. The method and apparatus use a high velocity oxygen fuel spray gun to coat a substrate with the non-melting polymers.
Abstract:
A method for forming a coating on a substrate using an atmospheric pressure plasma discharge. The method comprises introducing an atomised liquid and/or solid coating-forming material into an atmospheric pressure plasma discharge and/or an ionised gas stream resulting therefrom, and exposing the substrate to the atomised coating-forming material. The application also describes a method for polymerising a polymer forming material, and further to apparatus for forming a coating on a substrate.
Abstract:
The aim of the invention is to provide a method for producing insulations of electric conductors by means of powder coating which is characterized by an improved aging behavior compared to glass-mica or cast resin insulations and to also provide a powder appropriate for use in the inventive method. To this end, the powder is applied repeatedly up to a layer thickness of
Abstract:
A method for producing a self decontaminating surface to decontaminate chemical and biological contaminants that are deposited on the surface and decontaminatable through reaction with free hydroxyl radicals. The method first includes determination of a surface to be treated and which is exposable to ultraviolet light. Second, a coating of nanoparticles of a transition metal oxide, non-limitedly exemplified by anatase titanium dioxide, is applied to the chosen surface. Application of the coating is accomplished by spraying heated nanoparticles or clusters thereof from a feed stock onto the surface to form a nanoparticle coating, with the nanoparticles being at a temperature of at least about 750 DEG C upon exit from a spray apparatus and of a size between about 5 nm and 100 nm. Finally, the treated surface is exposed to ultraviolet light and water moisture, either naturally from the environment or artifically, to thereby catalytically form free hydroxyl radicals that thereafter react with the contaminants to render them generally harmless.
Abstract:
This invention relates to salt water, waste water, atmospheric and other corrosion resistant barrier apparatus and radioactive contamination containment barrier apparatus that are applied to a substrate, such as to metal, steel, concrete, rock, stone, ceramic material, tile, and the like, and methods for manufacturing the same. The apparatus (20) generally comprises an asphaltic mastic basecoat (24) and a thermpoplastic topcoat (26) which is at least partially melted and integrated into the mastic basecoat (24). Alternatively, the apparatus (20) further contains a solvent primer (28) which is applied to the substrate (22) prior to the application of the mastic basecoat (24).
