    Abstract: A method of coloring silica sand for use in coating a surface. The method includes the steps of selecting silica sand of a desired grain size and color, the preferred color being substantially white and grain size being any combination of thirty, fifty and eighty mesh. A coating having adhesive qualities is then prepared by one of air drying acrylic and vinyl emulsions or thermosetting phenolic, polyester and epoxy emulsions. To coat the silica sand, the silica sand to tumble or fall from an elevated position and is sprayed as it tumbles or falls with the prepared coating. The coated silica sand is then pulverized to break up clumped particles formed during application of the coating. A desired color mixture is obtained by mixing coated silica sand of different colors. The coated silica sand is then applied to a desired surface by one of spraying or using a trowel. Titanium dioxide may now be applied to the mixture after application to alter a gloss of the mixture.

    Abstract: A method for enhancing the cooling capability of a turbine component made from a ceramic matrix composite. The method improves the thermal performance of the component by producing a surface having increased cooling capacity, thereby allowing the component to operate at a higher temperature. The method tailors the available surface area on the cooling surface of the composite component by depositing a particulate layer of coarse grained ceramic powders of preselected size onto the surface of the ceramic matrix composite component. The size of the particulate is selectively tailored to match the desired surface finish or surface roughness of the article. The article may be designed to have different surface finishes for different locations, so that the application of different sized powders can provide different cooling capabilities at different locations, if desired. The compositions of the particulates are chemically compatible with the ceramic material comprising the outer surface or portion of the ceramic matrix composite. The particulates are applied using a slurry and incorporated into the article by heating to an elevated temperature without melting the matrix, the particulates or the fiber reinforcement.

    Abstract: The disclosure is for an apparatus and a method of adhering particulate matter to limited areas of adhesive on a moving web and enabling the use of a very limited amount of particulate matter so that material costs are minimized. The path of a moving web with zones of adhesive and with previously supplied loose particles is shaped to form a trough with substantially vertical sides, so that gravity clears the web of excess material as the web moves down and up through the trough. Meanwhile, the particles falling from the web, go into the bottom of the trough where they stay until they stick to a following portion of the web which has adhesive. The loose particles are thereby immediately recycled for use, without any exposure to other contaminating materials, and the amount of particulate material used approaches the ideal quantity which would be needed to cover only the adhesive areas.

    Abstract: A wear alloy coating (14) applied to a substrate material (12) by a cold spray process. Particles of the wear alloy coating material (16) are directed toward a target surface (18) of the substrate at a velocity sufficiently high for the particles to deform and to adhere to the target surface. The size and composition of the particles may be varied during the cold spray process to produce a coating with a varying property across the depth of the coating. Particles of the wear alloy material may be applied by cold spraying along with particles of a second material such as a lubricant or a ceramic material. For Group 5 hard facing materials, the size and distribution of the embedded carbide nodules may be controlled by controlling the selection of the carbide particles being sprayed. The cold spray process permits a wear alloy coating to be applied proximate a brazed joint or over a directionally stabilized or single crystal material without degrading the underlying material.

    Abstract: A system and a method for providing feedback control of the deposition of superabsorbent particles into an absorbent core at a specified rate are disclosed herein. A control system, such as a programmable logic control device, is used to receive feedback related to the operation of one or more elements of a vibratory feeder. Based on the feedback, the control system adjusts one or more elements of the vibratory feeder to synchronize the operation of the elements of the vibratory feeder. Particularly, the control system can be adapted to synchronize the deposition rate of superabsorbent particles into the absorbent core with the line speed of the absorbent core during ramp-up and ramp-down periods. Based on a predetermined line speed response during the ramp-up or ramp-down period, the control system can control one or more properties of the vibratory motion of a vibrator of the vibratory feeder in such a manner that the deposition rate of superabsorbent particles is proportional to the line-speed of the fibrous material being supplied so that a substantially uniform concentration of superabsorbent materials are deposited in the absorbent core during the ramp-up and ramp-down periods.
