    Abstract: Disclosed is a method of, and apparatus for, flame spraying particulate material utilizing the thermal energy of a very hot gaseous primary stream (27) produced in an oxy-fuel combustion chamber (11) combined with kinetic energy from a surrounding annular sheath of warm high velocity secondary air (28), the velocity of the said sheath of secondary air (28) being sufficiently close to the velocity of the primary stream (27) to avoid significant mixing between the two streams.

    Abstract: A refractory coating (28) extends over a portion of a diamond cutting blade (10) comprising a disc-shaped body (12) having an edge on which is positioned one or more cutting segments (14). One or more grooves (40, 42) are located in the sides of the blade body. The coating (28) is created by spraying a liquid tungsten carbide mixture onto each side of the blade (10) at a speed of over 3000 fps. The tungsten carbide is directed at the blade (10), resulting in a solidified metal coating on each side of the body and which fills in any overhang of the segment(s) beyond the blade body and the grooves in the blade body.

    Abstract: A method of coating a substrate comprises plasma spraying a prealloyed feed powder onto a substrate, where the prealloyed feed powder comprises a significant amount of an alloy of stainless steel and at least one refractory element selected from the group consisting of titanium, zirconium, hafnium, niobium, tantalum, molybdenum, and tungsten. The plasma spraying of such a feed powder is conducted in an oxygen containing atmosphere and forms an adherent, corrosion resistant, and substantially homogenous metallic refractory alloy coating on the substrate.

    Abstract: Polycrystalline silicon (84) is deposited on the interior surface of a shaped container (40). The silicon is deposited by reacting hydrogen (31) and a silicon bearing gas (30) in the presence of a high pressure plasma (22). The silicon body is separated from the shaped container by utilizing thermal expansion shear stress.

    Abstract: A first coating (e.g. WC-Co-Cr) is applied to a component such as spiral or screw-shaped rotor (e.g. of a downhole motor) by flame spraying (high-velocity oxy-fuel process). A ceramic slurry is applied and heated to form a second coating (containing chromium oxide). The coatings are impregnated with a solution of at least one soluble compound which is converted, on heating, into an insoluble substance which bonds with the coatings and causes densification of the coatings.

    Abstract: A method of operation of a plasma torch, an internal burner or the like to produce a hot gas jet stream directed toward a workpiece (s) to be coated by operating the plasma torch or internal burner at high pressure while feeding a powdered material (P1) to the stream to be heated by the stream and projected at high velocity onto a workpiece surface (S). The improvement resides in limiting the heating of the powdered material (P1) by the jet stream to that only sufficient to raise the temperature of the particles of the powdered material (P1) to a temperature lower than the melting point of the material, maintaining the intransit temperature of the particles to the workpiece below that melting point, while providing a sufficient velocity to the particles striking the workpiece to achieve an impact energy transformation into heat to raise the temperature of the particles to fusion temperature capable of fusing the material onto the workpiece surface as a dense coating (C).
