摘要： A cast iron material, particularly a ledeburitic cast iron material with a carbide content of at least 15 wt. % and a characteristic free, evenly distributed graphite formation is disclosed. In this case, the evenly distributed graphite formation may comprise graphite flakes and/or vermicular graphite and/or nodular graphite. Depending on the respective application (diameter (D) of the running gear seal, peripheral speed), the basic matrix may be realized in pearlitic and/or bainitic and/or martensitic form. Due to the high graphite content, the material has a thermal conductivity that is three to four times greater than that of white cast iron materials, wherein this provides the advantage that no scoring of the running gear seals occurs at high peripheral speeds (>5 m/s) and large diametrical dimensions of the seals (D >600 mm). In addition, the high carbide content of at least 15 wt. % provides an adequate wear resistance, and other alloying elements such as chromium, vanadium, molybdenum and nickel provide the material with a corresponding corrosion resistance. The aforementioned ledeburitic cast iron material with evenly distributed graphite formation can be used, for example, for the manufacture of axial face seals and cylinder liners.

摘要： Disclosed is a cast iron material, especially a ledeburite cast iron material which has a high carbide content of at least 15.0 percent by weight and is provided with a characteristic, free, evenly distributed graphite embodiment that can comprise flake graphite and/or vermicular graphite and/or nodular graphite. The basic matrix can be embodied in a pearlitic and/or bainitic and/or martensitic manner according to the application thereof (diameter (D) of the seal of the running gear, peripheral velocity). The thermal conductivity of the inventive material is three to four times greater than that of white cast materials as a result of the high graphite content, thus advantageously preventing seals of running gears from fretting in case of great peripheral velocities (>5 m/s) and large diameters (D>600 mm) of the seals. Additionally, the high carbide content of at least 15 percent by weight provides for good resistance to wear while additional alloying elements such as chromium, vanadium, molybdenum, and nickel provide the material with adequate resistance to corrosion. The disclosed ledeburite cast iron material featuring an evenly distributed graphite embodiment can be used for producing axial face seals and cylinder hushes, for example.
