Develop integrated performance of the new brake drum material

Automobile brake drum brakes are the most common, but also an important guarantee for safe driving cars. As the car continued to speed, heavy other direction, the original material can not meet the growing demand, the development of new comprehensive  cubic boron nitride  brake drum material is a priority. Vanadium Vanadium is compacted graphite iron pig iron as raw material to obtain a new compacted graphite cast iron, with excellent overall performance, is an ideal material for the brake drum. Studied elements rich in vanadium-titanium-vanadium alloy pig iron as raw materials, with a special creep treatment, inoculation process to obtain  synthetic diamond  CGI approach, the test analyzes the compacted graphite iron vanadium-titanium mechanical properties, microstructure , microstructure, wear resistance, thermal conductivity, thickness and sensitivity vermicularizing recessionary designed Diamond blade compacted graphite iron brake drums gating system. Compared with vermicular iron vanadium and titanium vanadium-titanium gray cast iron in the mechanical properties, microstructure, wear resistance and thermal conductivity differences, analyzes the causes.
