Title: Wolfgang Zimmermann: Innovator in Powder Metallurgy
Introduction
Wolfgang Zimmermann is a notable inventor based in Bonn, Germany. He has made significant contributions to the field of powder metallurgy, particularly in the manufacturing of cams for camshafts. His innovative approach has led to the development of a patented method that enhances the properties of these components.
Latest Patents
Zimmermann holds a patent for a "Method of manufacturing cams by powder metallurgy." This method involves creating cams that possess constant properties throughout their volume and are easily polishable. The process includes molding a powder mixture of iron powder, alloyed with carbide-forming elements, and graphite powder necessary for carbide formation. The blank is then sintered at a temperature slightly above its solidus temperature and compacted through hot-isostatic compression to achieve a density of at least 99% of the theoretical maximum.
