Technological factors influencing wear resistance of PCBN

WEI Jia-xin,LIN Feng,FENG Ji-fu(Guilin Research Institute of Geology for Mineral Resources,Guilin,Guangxi 541004,China)  
Technological factors of PCBN were analyzed based on various experiments.The result shows that grain size of cBN and raw material purifying treatment in vacuum are the main technological factors of PCBN wear resistance .Ti-Si-B was selected as bond and fine grain cBN was used to synthesize PCBN with the wear ratio over 1∶11000 under 5.0GPa~7.0GPa and 1673K~1873K.
