　　PCBN is prepared under high temperature and high pressure condition (HTTP)with WC+ Co as the matrix.Four kinds of adhesive systems are selected, namely no added adhesive, metal adhesive, the ceramic adhesive and metal-ceramic adhesive.The results show that the synthesis of PCBN has the overall best performance by using metal-ceramic adhesive.Adhesive Al may react with CBN to form AlB2 and AlN under HTHP.
