人造金刚石聚晶磨耗比与磁性关系的研究

采用不同的烧结工艺在高温高压下烧结出三批金刚石聚晶，然后采用WCF-2多用磁性分析仪和JS71-A型磨耗比测定仪对人造金刚石聚晶的磁性与磨耗比进行测量，并且分析了不同的烧结工艺和粘结剂和对聚晶磁性和磨耗比的影响。结果表明：人造金刚石聚晶的磨耗比与磁性之间存在着一定的关系，即一定的烧结条件下聚晶的磁性愈强反而它的磨耗比愈小。这样通过测量人造金刚石聚晶的磁化率可以对其进行初步分类，可以避免传统的有损检测，是一种可行的检测方法。

Research on Relationship between Abrasion Ratio and Magnetism of Synthetic Polycrystalline Diamond

Three groups of synthetic polycrystalline diamond were sintered under different conditions, then the magnetism and abrasion ratio of the synthetic polycrystalline diamond were measured by using WCF -2 and JS71 - A respectively, while the influence of different technics and bonds on magnetism and abrasion ratio were analyzed. The results indicated that there existed a certain relationship between the abrasion ratio and magnetism of the synthetic polycrystalline diamond under certain sintering condition, namely the bigger the magnetism, the smaller the abrasion ratio. By using this method. The synthetic polycrystalline diamond could be classed by measuring their magnetism, so as to avoid conventional defect checking.
