摩擦摩耗特性に及ぼす鋳鉄複合材の硬質相の影響

抄録

  To improve the brake performance of cast iron shoes, presently steadite is precipitated as a hard phase in alloyed cast iron, shoes used for rolling stock. To generate other hard phases in cast iron, we designed and manufactured cast iron composites, including Silicon Carbide (SiC) and Partially Stabilized Zirconia (PSZ) ceramic filters, and examined how these hard phases and their compositions in cast iron affect frictional and wear performance.
  The hard phases in cast iron increase the frictional coefficient, decrease the wear of block and increase the wear of disc. Steadite and SiC have the same effect as hard phases. These effects increase when the two are used in combination. On the other hand, PSZ is less effective as hard phases, even when added to steadite.
