摘要： Material treatment is effected in a treatment region (124) by at least two energy sources, such as (i) an atmospheric pressure (AP) plasma and (ii) an ultraviolet (UV) laser directed into the plasma and optionally onto the material being treated. Precursor materials (323) may be dispensed before, and finishing material (327) may be dispensed after treatment. Electrodes (e1, e2) for generating the plasma may comprise two spaced-apart rollers (212/214; 412/414; 436/438). Nip rollers (416/418; 436/438) adjacent the electrode rollers (412/414) define a semi-airtight cavity (440), and may have a metallic outer layer (437/439).

摘要： Energy, such as from a UV excimer laser (712), an infrared Nd:YAG laser (714) and an infrared CO2 laser (716) is directed through a nozzle (722) at the surface of a substrate (702) to mobilize and vaporize a carbon constituent (e.g., carbide) within the substrate (e.g., steel). An additional secondary source (e.g., a carbon-containing gas, such as CO2) (720) and an inert shielding gas (e.g., N2) are also delivered through the nozzle. The vaporized constituent element is reacted by the energy to alter its physical structure (e.g., from carbon to diamond) to that of a composite material which is diffused back into the substrate as a composite material.

摘要： Energy, such as from three different lasers, is directed at the surface of a substrate to mobilize and vaporize a carbon constituent element (e.g., carbide) within the substrate (e.g., steel). The vaporized constituent element is reacted by the energy to alter its physical structure (e.g., from carbon to diamond) to that of a composite material which is diffused back into the substrate as a composite material. An additional secondary element, which also contains carbon, may optionally be directed (e.g., sprayed) onto the substrate to augment, enhance and/or modify the formation of the composite material, as well as to supply sufficient or additional material for fabricating a diamond or diamond-like coating on the surface of the substrate. The process can be carried out in an ambient environment (e.g., without a vacuum), and without pre-heating or post-cooling of the substrate.

摘要： A wall ironing ring (8, 11, 14) for use in cooperation with a punch (1) to reduce the thickness of a sidewall of a cup (17) drawn from a laminate of a polyester film and sheet aluminium or sheet aluminium alloy has a frusto conical entry surface (24) to the ring which converges at an angle between 1° and 4° to a central axis perpendicular to the plane of the ring and terminates at a land of short length, measured at said axis; and divergent exit surface extends from said land at an angle in the range from 5° to 15°. The ironing ring may be made from a material having a thermal conductivity greater than 50 W/m°C used in cooperation with a like ring of smaller land diameter held apart from the first ring by a spacer (7) in which coolant is applied to the cup.

摘要： Laser energy is directed at a substrate to mobilize, vaporize and react a constituent (primary) element (e.g., carbon) contained within the substrate, so as to modify the composition (e.g., crystalline structure) of the constituent element, and to diffuse the modified constituent back into the substrate, as an adjunct to fabricating a coating (e.g., diamond or diamond-like carbon) on the surface of the substrate. This creates a conversion zone immediately beneath the substrate, which transitions metallurgically from the composition of the underlying substrate to a composition of the coating being fabricated on the surface of the substrate, which results in diffusion bonding of the coating to the substrate. Additional (secondary) similar (e.g., carbon) or dissimilar elements may be introduced in a reaction zone on and above the surface of the substrate to augment the fabrication of and to determine the composition of the coating. The laser energy is provided by a combination of an excimer laser, and Nd: YAG laser and a CO2 laser, the output beams of which are preferably directed through a nozzle delivering the secondary element to the reaction zone. The reaction zone is shielded by an inert (non-reactive) shielding gas (e.g., N2) delivered through the nozzle. A flat plasma is created by the lasers, constituent element and secondary element on the surface of the substrate and the flat plasma optionally extends around the edges of the substrate to fabricate a coating thereon. Pre-treatment and coating fabrication can be performed in conjunction with one another (in-situ). Alternatively, a substrate can be pre-treated to characterize its surface for subsequent coating. In either case, certain advantageous metallurgical changes are induced in the substrate due to the pre-treatment. The processes (pre-treatment and coating fabrication) are suitably performed in ambient, without preheating the substrate and without a vacuum. Substrates of numerous geometries, sizes and shapes, such as flat cutting tool inserts as well as round cutting tools, are readily coated in this manner. The lasers are directed at any suitable angle (including coaxial) relative to the substrate and/or the plasma.

摘要： Nanoscale particles and powders are made from a starting material, including larger-size starting particles and solid targets. Various techniques are disclosed all of which generally involve heating and decomposing the starting material with an energy source selected from the group consisting of laser, electric arc, flame and plasma. The various techniques disclosed herein all exhibit a high throughput and a nearly instantaneous rate of production of nanoscale powders for a variety of applications. In certain of the embodiments, cooling is required to prevent agglomeration of the nanoscale particles into larger (non-nanoscale) particles. The nanoscale particles are useful for painting, coating, joining, bonding, brazing, soldering, welding, etc. For example, thermal stresses normally associated with joining (e.g., brazing) may be alleviated by a low-temperature joining technique of the present invention. A low-temperature joining material is applied (as a paste, or as a powder spray, or as a tape, or as a paint, or as a putty) at the junction of two components desired to be joined together. Energy from a source such as a laser beam (for example an Nd:YAG or a CO2 laser) or by a flame, arc, plasma, or the like, is either "walked" along the joining material to react the entire amount joining material, or the joining material is self-sustaining and simply requires igniting a selected portion of the joining material by the energy source. In an exemplary application of the process, vanes are brazed to the bowl and/or to the shroud of an automatic transmission bowl (impeller or turbine) assembly, preferably using the low-temperature joining material. Systems for delivering the joining material and the energy are described. The fabrication of hollow vanes is described. The fabrication of shroudless bowl components, and stator components subsuming the function of the shroud are described.

摘要： Diamond materials are formed by sandwiching a carbon-containing material (106) in a gap between two electrodes (102 and 104). A high amperage current is applied by power supply (110) between the two electrode plates so as to cause rapid heating of the carbon-containing material. The current is sufficient to elevate the temperature of the carbon-containing material over 1000 DEG C. The carbon-containing material is then rapidly quenched by a heatsink (130). The heatsink can be in contact with one of the electrodes. This process is repeated until the diamond has formed. Also, a shielding or inert gas (140 and 142) is used during the process.
