Title: Wilfried Langner: Innovator in Cast Iron Technology
Introduction
Wilfried Langner is a notable inventor based in Friedberg, Germany. He has made significant contributions to the field of materials science, particularly in the development of advanced cast iron materials. His innovative work has led to the creation of a unique ledeburitic cast iron with high carbide content and evenly distributed graphite.
Latest Patents
Langner holds a patent for a ledeburitic cast iron material characterized by a carbide content of at least 15 wt. %. This material features a free, evenly distributed graphite formation, which may include graphite flakes, vermicular graphite, and nodular graphite. The high graphite content enhances thermal conductivity, making it three to four times greater than that of traditional white cast iron materials. This property prevents scoring of running gear seals at high peripheral speeds and large diametrical dimensions. Additionally, the high carbide content ensures adequate wear resistance, while alloying elements like chromium, vanadium, molybdenum, and nickel provide corrosion resistance. This innovative material is particularly useful for manufacturing axial face seals and cylinder liners.
