ＣＢＮ微粉粒度对合成ＰＣＢＮ的影响河南黄河实业公司技术中心（郑州４５０００３）刘书锋在ＰＣＢＮ生成过程中发现，ＰＣＢＮ产品质量波动有以下一些直观的表现：ＣＢＮ层表面渗出金属线，即所谓出现“长条纹”；ＣＢＮ层与硬质合金基片分离，即“脱层”；ＣＢＮ层局部...
Effect of CBN Particle Size on the Synthesis of PCBN The technology of PCBN production in PCBN production process has been found that the fluctuation of PCBN product has the following intuitionistic behavior: the surface of CBN layer exudes metal wire, that is, the so-called “long Stripes ”; CBN layer and cemented carbide substrate separation,“ delamination ”; CBN layer local ...
