| Popis: | Cu-based metal matrix, Ti coated and uncoated diamond composite were prepared by hot-press sintering in vacuum. The effects of the mixing time and the sintering temperature on the relative density, hardness and transverse rupture strength (TRS) of the matrix were studied. Structures of specimens sintered at different temperatures were studied by XRD. The TRS and wear resistant of coated and uncoated diamond segment were compared. The results show that the optimum mixing time is 20 hours; with the increase of sintering temperature, the relative density, hardness and TRS of the matrix firstly increase and then decrease; the TRS of diamond segment is lower than the matrix sintered at the same temperature and TRS of Ti coated diamond segment increased by 6.18% as compared with uncoated diamond segment; moreover the wear resistance of Ti coated diamond segment is better than that of uncoated diamond segment. |
