    Abstract: Known thermal spray apparatus are modified to achieve rough thermal spray coatings. Thermal spray apparatus operate to develop a plasma stream for introduction to a nozzle, for eventual application to the surface of a substrate. Upon entering the nozzle, the plasma stream is passed through a plasma cooling zone defined by a plasma cooling passageway, to a plasma accelerating zone defined by a narrowed passageway that expands into a plasma/particle confining zone for the discharge of material from the apparatus. The narrowed passageway of the apparatus is cooled, and the powder material to be applied by the apparatus is introduced into the plasma stream along the cooled, narrowed passageway. For the appropriate heating (melting) and acceleration of MCrAlY powder particles, for application to the substrate which is to receive the thermal spray coating, the ratio of the initial (plasma cooling) passageway relative to the narrowed (plasma accelerating) passageway is reduced from the more conventional value of about 4:1 to a ratio of 2:1 or less.

    Abstract: A bonding composition for a heat curable overlay coating for coating a substrate is provided. The bonding composition comprises phosphate ions, permanganate ions, at least one species of metal cation having a valence greater than +1, and water. The bonding composition has a pH in the range from about 1.5 to about 4.5 and is substantially free of chromate ions and molybdate ions. Preferably, the molar ratio of phosphate ions to permanganate ions in the bonding composition is in the range from about 2:1 to about 580:1 and the nonvolatile content of the bonding composition is in the range from about 10% (wt) to about 35% (wt). Aluminum ions am a preferred species of metal cation in the bonding composition. Overlay coating compositions are also provided containing metallic aluminum particles dispersed in the bonding composition of the invention.

    Abstract: A heat curable protective coating composition for providing barrier protection to a solid substrate. The coating composition comprises an aqueous solution of phosphate ions and nitrate ions and at least one species of metal ion having a valency greater than +1. The metal ions may be selected from the group consisting of aluminum ions, manganese ions, magnesium ions, cerium ions, cobalt ions, chromium (III) ions, nickel ions, iron ions, copper ions, and zinc ions. The composition has a pH in the range from about 0.5 to about 3.5. The composition is substantially free of chromate ions and molybdate ions. A cured topcoat is substantially clear and has a glossy appearance.

    Abstract: A spray booth for applying a coating to a substrate includes an outer chamber (12) containing a fluid therein having a predetermined first temperature and/or humidity and an inner chamber (14) in fluid communication with the outer chamber (12). The inner chamber (14) contains the fluid therein at a higher predetermined second humidity and/or temperature. The inner chamber (14) includes a fan (42) for recirculating a flow of the fluid at the second predetermined temperature and/or humidity therethrough and filters (34,36,44,46) for removing airborne contaminants. A temperature and/or humidity control device (58) exhausts a predetermined amount of the fluid from the inner chamber (14) out of the inner (14) and outer chambers (12) said exhausted fluid being essentially free of toxic contaminants, the exhaust of the fluid drawing fluid from the outer chamber (12) into the inner chamber (14) to lower the temperature and/or humidity in the inner chamber (14).
