Title: **Rainer Wenke: Innovator in PVD Coating Technologies**
Introduction
Rainer Wenke, an inventive mind based in Aachen, Germany, excels in the field of hard-material coatings and physical vapor deposition (PVD) technologies. With a total of two patents to his name, Wenke continuously contributes to advancements in the coating industry.
Latest Patents
Wenke's most recent patents focus on innovative processes that enhance the production of hard-material-coated components. His first patent outlines a process for producing a hard-material-coated component involving several key steps. These steps include the application of a layer of hard material in a PVD coating unit and subsequent structural processing of the outer surface of that layer. The invention particularly addresses challenges associated with producing a sufficiently smooth surface when dealing with thick coatings or those with a columnar structure. His solution introduces a method where the surface of the layer is blasted in a blasting device, utilizing an inorganic blasting agent with a grain size ranging from 1 μm to 100 μm and a sharp-edged grain shape, to enhance surface quality.
Wenke's second patent describes a PVD coating method and a corresponding device featuring a chamber that houses key components such as target cathodes, anodes, and substrate holders. The innovative aspect lies in the control device capable of delivering varying voltages to create a plasma environment essential for quality coating. Notably, the patent improves ion fraction from the target material which directly enhances the coating properties, thus addressing potential inefficiencies noted in prior designs.
