Abstract: Energy, such as from one or more lasers, is directed at the surface of a substrate to mobilize and vaporize a 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 can be the same as or different from the constituent element, 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 one or more coatings 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. Articles formed by the disclosed processes are described, including three-dimensional objects.

Abstract: Material treatment is effected in a treatment region 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. During processing, the material being treated may remain substantially at room temperature. Precursor materials may be dispensed before, and finishing material may be dispensed after treatment. Precursors may be combined in the plasma, allowing for in situ synthesis and dry treatment of the material. Electrodes (e1, e2) for generating the plasma may comprise two spaced-apart rollers which, when rotating, advance the material through a treatment region. Nip rollers adjacent the electrode rollers define a semi-airtight cavity, and may have a metallic outer layer. Loose fibers and fragile membranes may be supported on a carrier membrane, which may be doped. Individual fibers may be processed. Electrostatic deposition may be performed. Topographical changes may be effected. Various laser configurations and parameters are disclosed.

Abstract: In a method of joining a metal matrix composite (cermet) or ceramic tool material 1 to a metallic holder 2 by diffusion bonding through an intermediate metallic layer, the tool material 1 includes at least one carbide, nitride or boride in the matrix. In one example, the tool material includes titanium carbide and titanium nitride in the metal matrix. The intermediate metallic layer is chosen from a group consisting of nickel, titanium and tungsten. The tool holder metal 2 is a ferrous alloy. The intermediate metallic layer is placed between the tool material and the metallic holder, and heat and pressure are applied for a controlled period to diffusion bond the tool material to the metallic holder. Articles made by the method include a blank holder, a punch, a die and various wear surfaces of a continuous extrusion apparatus.

Abstract: Diamond materials are formed by sandwiching a carbon-containing material in a gap between two electrodes. A high-amperage electric current is applied between the two electrode plates so as cause rapid-heating of the carbon-containing material. The current is sufficient to cause heating of the carbon-containing material at a rate of at least approximately 5,000.degree. C./sec, and need only be applied for a fraction of a second to elevate the temperature of the carbon-containing material at least approximately 1000.degree. C. Upon terminating the current, the carbon-containing material is subjected to rapid-quenching (cooling). This may take the form of placing one or more of the electrodes in contact with a heat sink, such as a large steel table. The carbon-containing material may be rapidly-heated and rapidly-quenched (RHRQ) repeatedly (e.g., in cycles), until a diamond material is fabricated from the carbon-containing material. The process is advantageously performed in an environment of a "shielding" (inert or non-oxidizing) gas, such as Argon (Ar), Helium (He), or Nitrogen (N.sub.2). In an embodiment of the invention, the carbon-containing material is polystyrene (e.g., a film) or glassy carbon (e.g., film or powder). In another embodiment of the invention, the carbon-containing material is a polymer, fullerene, amorphous carbon, graphite, or the like. In another embodiment of the invention, one of the electrodes is substrate upon which it is desired to form a diamond coating, and the substrate itself is used as one of the two electrodes. This would be useful for forming a thin-film diamond coating on a cutting tool insert.
Abstract translation: 通过将含碳材料夹在两个电极之间的间隙中形成金刚石材料。 在两个电极板之间施加高电流电流，以使含碳材料快速加热。 该电流足以使至少约5,000℃/秒的速率加热含碳材料，并且仅需要施加一小时，以至少将含碳材料的温度升高至少 约1000℃。在终止电流时，对含碳材料进行快速淬火（冷却）。 这可以采取将一个或多个电极放置在与散热器（例如大型钢台）接触的形式。 可以重复地（例如，循环）将含碳材料快速加热并快速骤冷（RHRQ），直到由含碳材料制造金刚石材料。 该方法有利地在诸如氩（Ar），氦（He）或氮（N 2）的“屏蔽”（惰性或非氧化性）气体的环境中进行。 在本发明的一个实施方案中，含碳材料是聚苯乙烯（例如薄膜）或玻璃碳（例如薄膜或粉末）。 在本发明的另一个实施方案中，含碳材料是聚合物，富勒烯，无定形碳，石墨等。 在本发明的另一个实施例中，电极之一是需要形成金刚石涂层的衬底，并且衬底本身被用作两个电极之一。 这对于在切削工具刀片上形成薄膜金刚石涂层是有用的。
