Abstract:
A method of coating a vehicle wheel (10) to increase wear and corrosion resistance of the vehicle wheel (10), includes the steps of providing a vehicle wheel (10) and applying a wear and corrosion resistant coating (14) onto a surface of the vehicle wheel (10). The coating (14) is applied to at least a tire bead retaining flange (16, 24) of the vehicle wheel (10). The coating (14) is of particular use with vehicle wheels (10) made of forged aluminum. The coating (14) is selected from tungsten carbide, optionally including cobalt or chrome, a nickel-based superalloy, aluminum and silicon carbide, or stainless steel. The coating (14) is typically applied to a thickness of about 0.004 - 0.01 inch. The surface of the vehicle wheel (10) may be prepared by mechanically abrading the surface or chemically etching the surface of the vehicle wheel (10). The coating (14) may be applied by cold spraying, thermal spraying, or triboelectric discharge kinetic spraying and other similar processes.
Abstract:
The invention concerns a process for coating an object with a layer of fluorine containing material at elevated temperature. The material applied for coating has a measurable vapour pressure at elevated temperature and contains organic fluorine.
Abstract:
The invention relates to a plane body which is exposed to weather hazards and which is used for building purposes, especially with smooth, porous and/or a micro-structured surface such as a clinker, a roof tile or a shingle. In order to protect it from the growth of moss, a coating having much stronger water- or dirt-repellent characteristics than said body is provided.
Abstract:
The invention relates to the production of a coating, especially on aluminum. According to the invention, a coating is applied on the aluminum, said coating is heat-treated and said coating is further treated. The inventive method results in improved surface properties.
Abstract:
Plasma spraying of particulate thermotropic liquid crystalline polymers onto the surfaces (14) of composite and metallic structures. The present plasma spray process employs a conventional direct current electric arc plasma spray gun (12) in which an inert plasma gas is introduced, caused to swirl, and discharges as a rotating plasma flame having an exceptionally high temperature, above about 14000 DEG K, into which the particulate liquid crystal polymer is discharged for melting and propulsion onto the target surface (14). The target surface (14) preferably is preheated, and the molten particles deposit and cool to form a build up of the desired thickness. Cooling is regulated by post-heating the deposit to a temperature between about 200 DEG F and 500 DEG F.
Abstract:
PURPOSE: A method for forming a thermal barrier coating on hot-gas-path components of a gas turbine is provided to do a thermal barrier coating without stopping the gas turbine. CONSTITUTION: A method of the thermal barrier coating layer during the operation of the gas turbine comprises: a step of adding the organic compound which contain in the fuel the silicon under the first condition; and a step of adding the organic compound which contain in the fuel the silicon under the second condition. A base layer and a porous layer include silicon dioxide which becomes with the reaction of the organic compound and fuel gas. The thickness of the base layer 1 ~ 5 μm The porosity of the porous layer 60%, and the thickness more than 5 μm.
