Latest Patents

Fröhlich's latest inventions reflect his expertise in creating revolutionary materials. His first patent describes an **open-porous metal foam body and a method for fabricating the same**. This remarkable invention comprises an iron-based alloy containing 15 wt % or more of chrome and 5 wt % or more of aluminum. The manufacturing process involves using a semi-product formed of iron or an iron-based alloy that has lesser concentrations of chrome and aluminum. Notably, the final product features a uniformly coated surface and open pores, thanks to the application of an iron-chrome-aluminum alloy combined with an organic binding agent. The process culminates in a heat treatment that induces sintering under a reduction atmosphere, allowing optimal diffusion of alloy elements for a refined end product.

Another of Fröhlich's significant patents includes a **catalytic converter support body**. This invention features a honeycomb body arranged with at least three metal layers, specifically designed to improve catalytic efficiency. The metal layers are cleverly structured from metal-foam layers and are assembled into a spiral formation, providing superior structural integrity and functionality. A notable innovation in this design is the incorporation of a corrugated sheath between two planar metal-foam layers, enhancing the overall performance of the catalytic converter.
