Patent number: 8137459Abstract: The inventive method for producing nanoparticles for ferrofluids by electron-beam evaporation and condensation in vacuum, consists in evaporating an initial solid material and in fixing nanoparticles to a cooled substrate by means of a solidifiable carrier during vapour condensation, wherein a solid inorganic 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 magnetic carrier material for fixing nanoparticles. The method also consists in simultaneously evaporating the initial material and the carrier composition by electron-beam heating. The vapour is deposited on the substrate, the temperature which is lower than the melting point of the carrier material, and the condensate of the magnetic material nanoparticles, which have a size and are fixed in the carrier, is produced. The particle size is adjusted by setting the specified temperature of the substrate during vapour deposition.Type: GrantFiled: August 22, 2007Date of Patent: March 20, 2012Assignee: State Enterprise “International Center For Electron Beam Technologies of E.O.

Patent number: 6669989Abstract: The invention relates to a method and apparatus for the production of protective coatings on parts. A coating formed in accordance with the invention has a chemical composition and structure gradient across its thickness. The coating is obtained by heating of a composite ingot including a body and at least one insert disposed within the body. As the composite ingot is heated it sequentially evaporates to produce a vapor with a chemical composition varying over the evaporation time period. The composition of the body and composition and location of the insert within the body function to determine the chemical composition of the vapor at any time. Condensation and/or deposition of the vapor onto a substrate forms the inventive coating.Type: GrantFiled: November 7, 2001Date of Patent: December 30, 2003Assignee: International Center for Electron Beam Technologies of E.

Patent number: 6211489Abstract: A press welding process which can be used in such industries as car-making, production of hot-water boilers, industrial and civil construction, in construction of pipelines using small and medium diameter pipes, for welding parts with a solid and developed cross-section, as well as for joining parts to form a T-joint. A magnetically impelled arc butt welding is achieved, that, during heating, the controlled continuous displacement of the parts being welded is performed where the gap between the parts edges is kept constant. The value of the welding arc voltage is used as the parameter for the gap size adjustment, and the moment of achievement of the required temperature on the edges of parts being welded, is determined by the length of the relative displacement of the parts, and when the assigned values of displacement have been reached, the speed of the arc movement along the edges of the parts being welded, is programmed.Type: GrantFiled: January 21, 1999Date of Patent: April 3, 2001Assignee: E.O.
