| Abstract: | Cu-matrix bonding diamond tool bits were prepared by hot-pressing sintering. The effect of sintering temperature and pressure on properties of was investigated. The results showed that sintering temperature has significant effect on the hardness and flexural strength of Cu-matrix bonding diamond tool bits, while sintefing pressure has less effect on the bits properties. The optimal sintering technique was that the sintering temperature was 700℃ and the sintering pressure was 20 MPa. Moreover, the stress-strain diagram of Cu-matrix bonding diamond tool bits is neither metal nor ceramics material character. |
