Latest Patents

Hotzsch's latest patents include a "Compound body of vacuum-coated sintered material and process for its production." This innovation addresses the shortcomings of traditional coated materials, which often exhibit thermal, mechanical, and chemical instability. His improved eco-friendly vacuum deposition process applies a layer of Al₂O₃ to a sintered material carrier at temperatures up to 800°C. This layer is completely crystalline and possesses a compressive stress of at least 1 GPa and a hardness of at least 20 GPa. The resulting compound bodies are particularly useful for cutting treatments, such as cemented carbide inserts.

Another significant patent is the "Vacuum-coated compound body and process for its production." This invention also tackles the issues of instability in coated materials. The process involves applying an Al₂O₃ layer to a metal or alloy carrier at a maximum temperature of 700°C. Similar to his other patent, this layer is crystalline and exhibits the same impressive mechanical properties. These compound bodies are designed for various cutting tools, including drills, milling cutters, reamers, broaches, and saw blades.
