    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.

    Abstract: 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.

    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. The method of the present invention includes the additional steps of using the energy to move a carbon constituent element in a sub-surface zone of the substrate towards the surface of the substrate, vaporizing selected amounts of the carbon constituent element to produce a vaporized carbon constituent element, reacting the vaporized carbon constituent element to modify its physical structure and properties, reacting the vaporized carbon constituent element to modify its physical structure and properties, and fabricating the diamond coating from the reacted vaporized carbon constituent element.

    Abstract: 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.

    Abstract: Solid tungsten carbide is the popular material for these combinations tools. High resultant side forces on the tool during the thread milling phase are caused by relatively high circumferential engagement of the tool and a very low feed per tooth (chip thickness). A combined hole making, threading and chamfering tool with staggered thread cutting teeth doubles chip thickness and reduces side forces (resulting in less engagement), consequently allowing the feed rate to be increased while reducing thread milling time. In addition, this arrangement also reduces tool chatter, thus providing a smoother surface finish in the thread. In one form, the cutting teeth are formed on one or more removable inserts, facilitating replacement or substitution thereof.

    Abstract translation: 固体碳化钨是这些组合工具的常用材料。 在螺纹铣削阶段，工具上产生的高结果侧力是由刀具的相对较高的圆周接合和每齿的非常低的进给（切屑厚度）引起的。 具有交错螺纹切削齿的组合孔制造，螺纹和倒角工具使芯片厚度加倍，减少侧向力（导致较少的接合），从而允许进给速度增加，同时减少螺纹铣削时间。 此外，这种布置还减少了工具颤动，从而在螺纹中提供更平滑的表面光洁度。 在一种形式中，切割齿形成在一个或多个可移除的插入件上，便于更换或替换。

    Abstract: 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.
