摘要
金刚石的静载强度 ,最早的定义在数值上是与粒径的平方成反比 ,以后的国标又以与粒径的一次方成反比的关系来定义。文章通过对工具中金刚石抗磨损能力的分析 ,认为以反比于粒径的 0 .73
The original definition of diamond static load strength is inverse proportion with the square of grain size.Afterward,it is defined to be inverse proportion with first power of grain size in the national standard.By analyzing wear resistance of diamond in the tools,it is appropriate that diamond static load strength is in inverse proportion to the power of 0.735 of grain size.
