    摘要： Thermal stresses normally associated with brazing are alleviated by a low temperature brazing technique of the present invention. A low-temperature brazing paste, preferably suitable to be melted at temperatures of no greater than 200.degree. C. (e.g., 100-200.degree. C.), containing nanoscale (.ltoreq.100 nanometer) size particles of gold, cadmium, copper, zinc, tin, lead, silver, silicon, chromium, cobalt, antimony, bismuth, aluminum, iron, magnesium, nitrogen, carbon, boron, and alloys and composites of these materials, is applied as a bead or as a powder spray at the junction of two components desired to be joined together. Energy from a source such as a laser beam (for example a CO.sub.2 laser, an Nd-Yag laser or an excimer laser), flame, arc, plasma, or the like, is "walked" along the brazing material. The energy beam is sufficient to cause melting and re-crystallization of the nanoscale-particle-containing brazing paste. In an exemplary application of the process, blades (vanes) are brazed to the housing and/or to the shroud of an automatic transmission impeller assembly, preferably using the low-temperature brazing paste containing nanoscale (.ltoreq.100 nanometer) size particles of gold, cadmium, copper and/or zinc, or other suitable nanoscale brazing materials.

    摘要： 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.

    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.

    摘要： A method for producing well-crystallized adherent diamond layers on WC—Co substrates. An array of focused laser beams is scanned across the WC—Co sample. Useful lasers include the excimer, YAG:Nd, and carbon dioxide types. The process is conducted in open air with carbon dioxide and nitrogen gases delivered for shrouding the substrate. A luminous plasma is found a few mm above the WC—Co insert. The duration of the deposition process in a typical case is approximately 40 s. This typically gives 20-40 &mgr;m thick coatings. The vertical growth rate is about 1 &mgr;m/s.

    摘要： A diamond coating formed on a WC—Co substrate prepared through a process including employing a plasma and a variety of interactions from a multiple laser system demonstrates exceptional adhesion and indicates a durable cubic diamond structure. The coating on the WC—Co substrate is typically between 25 and 40 &mgr;m thick and has an average crystal size of between 10 and 20 &mgr;m. Various methods of confirming the cubic diamond structure of the coatings have been employed. The adhesion of the diamond coating to the substrate is very strong. An electron microprobe analysis shows tungsten and cobalt atoms incorporated into the film and a layer depleted in cobalt exists at the diamond-WC—Co interface. Particulates of WC—Co—C alloy are spread over the top surface, apparently formed by condensation from the vapor phase of metal-containing molecules. Carbon is confirmed as being the main component of the surface layer.

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.

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. The process is truly heteroepitaxial, and is suitable for treating substrates of complex geometries, and coating all sides of such substrates either evenly or selectively. The process may also be used as an adjunct to conventional CVD-type processes, to eliminate the need for heating the substrate to high temperatures. Articles formed by the disclosed processes are described, including three-dimensional objects.
