摘要： 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 DEG 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 DEG 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 (At), Helium (He), or Nitrogen (N2). 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.

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 method for providing a glassy carbon coating to a substrate for producing a protected substrate is disclosed. The glassy carbon coating may formed through use of a plasma gas gun delivering a plasma to a substrate. In the plasma gas embodiment, powdered carbon or an alternative polymerizable material is introduced into the ionized gas stream for application to a substrate. According to an alternate embodiment of the present invention, the substrate is dipped and coated with a polymerizable material and the coated substrate is exposed to a heat source such as one or more lasers, thus transforming the coating into a glassy carbon coat. The coat produced through any application method of the present invention provides a barrier to corrosion, erosion, wear and high heat. A substrate so coated may be exposed to extreme environments, high heat, low heat, wet, dry, or surface contacting without showing any significant degradation.
