Method and device for applying or embedding particles onto or into a layer applied by plasma coating
Patent number: 9238862Abstract: A method for applying or embedding nanoparticles or microparticles of any substance in a defined manner onto or into a layer to be applied to a substrate surface by plasma coating before, during or after the plasma coating operation in a magnetron or plasmatron. The particles are introduced from the outside into the vacuum chamber of the magnetron or plasmatron via at least one pressure stage. The particles are spatially distributed in the plasma space between the target and the substrate. The particles in the plasma space are preferably exposed to an electric field generating a movement of the particles toward the substrate. It is advantageous for this purpose if the particles are electrically charged before being introduced into the plasma space.Type: GrantFiled: October 9, 2009Date of Patent: January 19, 2016Assignee: BAM Bundesanstalt fuer Materialforschung und—PruefungInventor: Uwe Beck -
Patent number: 9074870Abstract: The invention relates to a method and a device for sintering objects by means of time-resolved detection of two- or three-dimensional surface profiles and, optionally, by means of temperature measurement in a high temperature furnace on the basis of optical measurement methods. During sintering, each surface point on an object can be measured for its position and, optionally, its temperature, and a change can be determined by successive measurements. The measured change additionally permits control of the sintering regime. The method comprises the steps of: placing an object 4 into a high temperature furnace 5; heating the furnace 5; generating a two- or three-dimensional surface profile at least of a subregion of the object 4 by: irradiating the object 4 with light from a light source 2a; detecting the light scattered by the object 4 with the aid of a detector 2b; determining the geometric surface profile from the detected light.Type: GrantFiled: May 19, 2009Date of Patent: July 7, 2015Assignees: BAM Bundesanstalt Fuer Materialforschung und- Pruefung, Nokra Optische Prueftechnik und Automation GmbHInventors: Ulrich Marzok, Ralf Müller, Reinhard Schadrack, Michael Krauhausen
