Latest Patents

Wohlrab's recent patents showcase his expertise in creating cutting-edge layer systems and deposition methods. One of his notable patents is for a "Layer system with at least one mixed crystal layer of a multi-oxide." This innovation involves a Physical Vapor Deposition (PVD) layer system specifically designed for coating workpieces. The system includes at least one mixed-crystal layer of a multi-oxide with a unique composition of (Me1Me2)O, where Me1 and Me2 are distinct elements such as Aluminum (Al), Chromium (Cr), Iron (Fe), Lithium (Li), Magnesium (Mg), Manganese (Mn), Niobium (Nb), Titanium (Ti), Antimony (Sb), or Vanadium (V). The crystal lattice of this layer exhibits a corundum structure, distinguished by an x-ray diffractometrically analyzed spectrum characterized by at least three lines associated with this structure.

Another significant patent by Wohlrab pertains to a "Method for depositing electrically insulating layers." This invention involves a novel technique for operating an arc source, where an electric spark discharge is ignited on the surface of a target. The process allows for the simultaneous feeding of direct current at a constant voltage and a pulsed current produced by a periodically applied voltage signal. The enhancement of the voltage at the arc source is achieved over a few microseconds, contributing to flexible voltage signal shapes.
