I went to the branch real estate office instead of the main one I work thru...and the guy is in ....never mind...well, we have 3 branches, I think I will stay out of the main Office! LOL came back to see a Buck..and all my WOWs...wow- wowwow!!! ! Core position stragety is what we have to do, get back to basis and just read the wensite over..., get back to basis and just read the website over... ..., get back to basis and just read the website over... ..., get back to basis and just read the website over... Chuckame2 or 3? rhombic.com I pull stuff outta here on that last long post so here is the full thing and notice the date: No date here so I had clicked this paragraph to find this WEBSITE TEXT- I referred to it earlier tonite as May NR TEXT- WRONG: The manufacturing of disperse composite materials (DCM) is according to the invention realized by a plasma processing of high efficiency, and has specific properties for high temperature superconductors.RE: Method and Equipment for manufacturing Disperse Composite Materials Prof. Dr.Dr. Heinrich Hora, Birkernalleee 18A, 85586 Poing

Summary:
The manufacturing of fine dispersed materials of the size form nanometers with a homogeneous interior and an additional coating is according to the invention realized by a plasma processing of high efficiency. These disperse composite materials (DCM) have specific properties of abrasion or wear resistance, friction, catalytic action or sintering e.g. for high temperature superconductors.
Description:
The invention refers to chemistry, metallurgy, material sciences and micro-technology for manufacturing disperse composite materials as powders which consist of small particles and which are covered with another material. These dispersed composite materials (DCM) can be produced as catalysts, as abrasive, wear-resistant grinding material of high strength of with surfaces without magnetic permeability. A further use of the composite materials applies the structural properties of very small size particles of very high strength as these are needed for composite resistors, or during the process of soldering or welding of ceramic materials (high temperature superconductors, rigid electrolytes etc.) with metals.
In production of disperse catalysts one of the important problems is to produce catalytic coatings thin and strongly connected with an initial disperse material (carrier). It is especially necessary when expensive metals such as platinum, gold, iridium, palladium, or rhodium are used as catalytic active components of coatings since the coating has to have a strong adhesion to the carrier to provide a high life time of the catalyst.
In practice of creating new materials there is a wide use of various disperse composite materials on the base of diamonds, oxides, silicon silicates or nitrides, titanium, tungsten, zirconium, vanadium, molybdenum, boron, aluminum etc., covered with shells of one or several metals: nickel, cobalt, silver, copper, molybdenum, tungsten, titanium, aluminum, tin, lead, zinc, zirconium, metals of the platinum group, etc. These materials are used in the processes of depositing various (for example, strengthening, abrasive, abrasive resistant, heat resisting with no magnetic permeability, and also as a conductive phase in composite resistor) coatings upon the product as well as for creating high-strength structural composite materials. Metalization of initial powders leads to the absence of contacts between the particles of the carrier material among themselves, i.e. to matrix structure of mascroscopic compositions in the product. Besides the deposition of coatings, being diffusion barriers for atoms of initial powders, allows to suppress recrystallization during the process of manufacturing the product by sintering method. It opens a possibility of making the stable materials with a super small sized grain. Besides that the DCM can be used as an intermediate material during soldering or welding various ceramic and other nonmetal items with metals, for example, as a solder for junction of high temperature superconductors (HTSC) of electrolytes with current leads. Coating material for this method can be, for example, silver, which is one of few metals not interacting with oxygen HTSC materials and used for treading low resistive contacts.
Among the requirements for DCM there is a high adhesion of coatings to the disperse carrier and controllability of the coating process necessary to take place under the given parameters of particle structure and content and leading to homogeneity of the produced powders.
All the hitherto known manufacturing methods for these materials have a number of shortcomings. These are: insufficient continuity of the obtained coating, poor adhesion of the deposited component to the particles of the initial material, formation of sinters, containing a few particles of an initial material inside the same shell that results in heterogeneity of the produced powders and, in the final analysis, in a strong degrading of the strength of the produce, its wear resistance and applicability. One of the manufacturing methods coming closest to the methods of the following invention is the plasma deposition (H.S.Shin, D.G. Goodwin, Deposition of diamond coatings on articles in a microwave plasma enhanced fluidized reactor, Materials Letters Vol 19, p. 119-122 (1004); R. Quellette, M. Barbier, P.Cheremisionoff, Low Temperature plasma technology applications, Ann Arbor Science publications, Ann Arbor, 1980).
The difficulties of the hitherto known methods are overcome according to the invention described in the following equipment and method where – according to the invention – the deposition process is essentially better controlled and the exactness of the deposition process of the coating components onto the fine dispersed basic material is performed. Accordingly the sintering of the carrier material is avoided during the process of deposition of the covers and simultaneously the adhesion of the cover on the carrier is improved.
The equipment and the method for producing the DCMs consists in filling of a working chamber with a plasma producing gas which is being excited to plasma, and in injection of the dispersed (dusty) base material as well as the one or other components of the coating material being in the gas or vapor phase.
A special application of this method and apparatus is the manufacturing of coatings which leads to a very low cost conversion of long lived radio nuclides (mostly from nuclear reactors) into stable nuclides or the elimination of plutonium by transmutation into uranium. It is well known that nuclear reactions in host metals (nickel, palladium, titanium, zirconium, thorium etc.) for high concentrations of hydrogen ions of its isotopes are used which are occuring as low energy long time processes in nuclear distances in the range of picometers (H.Hora et al. Transactions fo the American Nuclear Society, 766, 144 (1997)). It is essential that very high surfaces with multilayers of appropriate host metals are made as it is done according to the invention with the DCMs. The material added to the plasma for production the coatings (on glass or similar carrier materials of the size around 10 um) is then one or in a sequence further mentioned host metals as well as charges of the long time radio nuclides for transmutation, preferably into the surfaces or in interfaces.
