    Abstract: A primer for flame sprayed polyolefin comprises an epoxy resin, preferably of low molecular weight and/or low viscosity; and an amine hardener, part of which becomes highly reactive on exposure to open flame, providing near instant cure of the composition under flame spray conditions. The invention is unique that it provides strong adhesion to steel, even where the surface preparation is less than ideal, as well as to concrete and other substrates. The primer eliminates the need to preheat the substrate. The primer has strong adhesion to the topcoat polyolefinic material, especially to a functionalized topcoat. The composition withstands open flame and does not char under polyolefin flame spray conditions, nor does it run or sag, and it is not prone to failure as it cools after the application of the polyolefin.

    Abstract: A method for chemical vapor deposition using a very fine atomization or vaporization of a reagent containing liquid or liquid-like fluid near its supercritical temperature, where the resulting atomized or vaporized solution is entered into a flame or a plasma torch, and a powder is formed or a coating is deposited onto a substrate. The combustion flame can be stable from 10 torr to multiple atmospheres, and provides the energetic environment in which the reagent contained within the fluid can be reacted to form the desired powder or coating material on a substrate. The plasma torch likewise produces the required energy environment, but, unlike the flame, no oxidizer is needed so materials stable in only very low oxygen partial pressures can be formed. Using either the plasma torch or the combustion plasma, coatings can be deposited and powders formed in the open atmosphere without the necessity of a reaction chamber, but a chamber may be used for various reasons including process separation from the environment and pressure regulation.

    Abstract: A method of manufacturing a metal and polymeric composite article by the following steps. Droplets of spray deposited metal and spray deposited polymeric material are combined to form an article having the polymeric material interspersed within the metal. A carrier or form that shaped to receive the metal and polymeric layers is provided. The carrier may be made either stationary or movable. Layers of spray deposited metal and spray deposited polymeric material are applied atop the carrier. The spray deposited metal is between 90 and 95 percent by volume of the article. The polymeric layers do not completely cover the metal layers. Succeeding spray deposited metal layers contact bond to previous metal layers. The polymeric material between imbedded between the interconnected metal layers.

    Abstract: A flame coating machine for coating field joints of a pipeline has a flame spray system having two flame spray units configured for heating and/or coating with a thermoplastic polymer an annular junction portion and two annular end portions of an existing coating delimiting the annular junction portion; a control system having two temperature sensors configured for acquiring temperature values along the surface collectively defined by the annular junction portion and the annular end portions, and a control unit configured for actuating the flame spray unit in a polymer flame spraying mode or in a flame heating mode as a function of the detected temperature values and at least one threshold value.

    Abstract: A retaining ring for a polishing system is disclosed. The retaining ring has a process-resistant coating over a portion thereof. The process-resistant coating is a thin, smooth, conformal layer that is resistant to wear and chemical attack. The process-resistant coating is formed by a method that includes vapor deposition from a precursor gas mixture, which may deposit polyparaxyxylene from a gas mixture comprising paracyclophane. Adhesion of the process-resistant coating to the retaining ring may be enhanced by treating the surface of the ring prior to forming the coating. Resistance of the coating to the process may be further enhanced by treating the surface of the coating with an etching or deposition gas to impart texture.
