20150122633 | HIGH-POWER PULSE COATING METHOD - The invention relates to a method for determining the reactive gas consumption in a coating process using plasma, comprising the following steps: a) admitting reactive gas into a coating chamber, wherein the corresponding reactive gas flow is measured and, at the same time, the partial pressure prevailing in the coating chamber is measured, without igniting a plasma; b) admitting reactive gas into a coating chamber, wherein the corresponding reactive gas flow is measured and, at the same time, the partial pressure prevailing in the coating chamber is measured, wherein a plasma is ignited. The method is characterized in that the steps a) and b) are carried out in the case of a plurality of different reactive gas flows and thus the partial pressure dependence of the reactive gas flow can be determined both with plasma or without plasma,—in the case of a given partial pressure, deduction of the reactive gas flow value that has been determined without plasma from the reactive gas flow value that has been determined with plasma and equating the difference to the reactive gas consumption. | 05-07-2015 |

20110001079 | METHOD FOR PRODUCING NANOPARTICLES FOR MAGNETIC FLUIDS BY ELECTRON-BEAM EVAPORATION AND CONDENSATION IN VACUUM, A MAGNETIC FLUID PRODUCING METHOD AND MAGNETIC FLUID PRODUCED ACCORDING TO SAID METHOD - The invention relates to producing magnetic fluids and to novel material synthesis. The inventive method for producing nanoparticles for magnetic fluids by electron-beam evaporation and condensation in vacuum consists in evaporating an initial solid material and in fixing nanoparticles of this material on a cooled substrate by means of a solidifiable carrier during vapour condensation, wherein a solid inorganic magnetic material, which is selected from a group containing metals, alloys or oxides thereof, is used as an initial material and a solid liquid-soluble material is used as a carrier material for fixing nanoparticles of the magnetic material. The method further consists in simultaneous evaporating the initial material and carrier composition, in which the carrier concentration ranges from 99 to 70%, by electron-beam heating. The vapour is deposited on the substrate, the temperature of which is set and maintained at a specified value, which is lower than the melting point of the carrier material, and the condensate of magnetic material nanoparticles, which have specified size and are fixed in the solid carrier, is produced. The particle size is adjusted by setting the specified temperature of the substrate during vapour deposition. A solid inorganic material, which is selected from a group containing salts of alkali and alkali-earth metals and mixtures thereof is used in the form of a carrier material used for fixing nanoparticles. The nanoparticles are extracted from the above-mentioned condensate by diluting it in at least one type of liquid, and by stabilizing by a surface-active agent. A method for producing a magnetic fluid, which contains magnetic material nanoparticles of the specified size, is also described, in which it is produced by dissolution in at least one fluid of the condensate of magnetic material nanoparticles of the specified size fixed in the solid carrier, which nanoparticles are produced by simultaneous electron beam evaporation with subsequent deposition on the substrate, the temperature of which is set and maintained at a certain level below the temperature of the carrier material melting, of a composition of solid inorganic magnetic material selected from a group, which includes metals, alloys and their oxides, and of a solid carrier soluble in the fluid, which fixes the nanoparticles, and which is selected from a group of inorganic materials, including the salts of alkali, alkaline-earth metals and their mixtures, and stabilization of the nanoparticles in the above fluid by a surface-active agent. | 01-06-2011 |
