Latest Patents

One of his latest patents is a method for producing a sliding surface. This innovative method involves applying a coating of amorphous carbon to a machine element's surface and locally heating it with a laser. The heating process is carefully controlled to remain below the evaporation temperature of the coating, resulting in a local volumetric increase and a thicker layer of the coating. This technique creates a surface structure with multiple elevations, transforming the amorphous carbon into graphite through localized heating.

Another significant patent by Dupke is for a cam follower designed for the valve train of an internal combustion engine. This cam follower is uniquely shaped as a U-shaped lever made from steel sheet without the need for machining. It features a valve stem support groove at one end, with lateral guide walls formed through chipless shaping. This design reduces stress and minimizes the risk of cracks, enhancing the durability of the component.
