A non-nanocrystalline particulate containing a polymorphic material in an atmospheric phase is introduced into a high-velocity gas jet. The projected particulate is allowed to impact a substrate at a velocity effective to cause at a least a portion of the polymorphic material to transform to a nanocrystalline, high pressure phase.

Abstract: A system for fine feature spray deposition includes a substrate platform for supporting a substrate on which the features are to be deposited. A spray assembly is provided which includes a spray source for providing a stream of material to be deposited on a substrate, a collimator which is positioned in a path of the stream from said spray source and an aperture assembly, which is positioned downstream of the collimator with respect to the spray source and above the substrate platform. The aperture assembly defines at least one opening to pass a portion of the stream of material onto a surface of the substrate. A drive mechanism is provided which is coupled to at least one of the spray assembly and the substrate platform for inducing relative motion there between. A controller is coupled to the spray assembly and the drive mechanism to control the relative motion and the stream of material. The system allows fine features to be printed directly on a substrate with requiring a predefined mask.

Abstract: An apparatus for performing in-situ curvature measurement of a substrate during a deposition process is provided which includes a clamp for retaining the substrate near one end while leaving the opposite end free. A plurality of displacement sensors are arranged in a spaced apart fashion along the length of the substrate and are directed to a surface of the substrate opposite a surface to be coated. Each sensor provides a signal to a computer corresponding to a position of the substrate relative to the sensor. The computer receives and stores data from the displacement sensors to determine a stress evolution during a deposition process and to determine a coating modulus based upon a resultant curvature of the substrate.

Abstract: A molybdenum-based composite powder for thermal spray applications. The composite powder includes a molybdenum-chromium, molybdenum-tungsten, or molybdenum-tungsten-chromium alloy dispersion strengthened with molybdenum carbide (Mo2C). The molybdenum-based composite powder may be combined with a nickel-based or cobalt-based alloy to form a two-phase powder blend. The coatings from such powders are made up of molybdenum-based alloy lamellae and, in the two-phase embodiments, nickel-based or cobalt-based alloy lamellae. The coatings exhibit improved corrosion resistance and strength while retaining good sprayability.
