【摘要】 根据我们的实践与调研 ,就进一步提高我国金刚石工具质量的有效途径进行了探讨。我国金刚石工业必须并可能为金刚石工具制品提供性能稳定、粗颗粒、热稳定性好的高强金刚石。为提高金刚石把持力 ,有必要在粘结剂中采用强碳化物形成元素或镀覆金刚石。胎体用粉末宜使用超细粉末与预合金化粉末 ,以便改进胎体性能。在刀头生产中推广制粒工艺 ,以优化金刚石分布 ,提高冷压工艺的性能和效率 ,降低模具消耗。烧结工艺中采用保护气氛热压烧结工艺与设备。在绳锯串珠生产中采用热等静压 (HIP)与高温钎焊工艺。激光锯片生产中完善刀头烧结工艺与焊接工艺参数 ,生产高质量的激光锯片更多还原

【Abstract】 On the basis of our practice and investigation, some effective measures to further improve the quality of diamond tool are discussed. First of all, good performanced, coarse crystal, thermally stable, ultrahigh grade diamonds are needed. In order to improve the diamond retention in the bonds, it is suggested to add carbide former element metal in bond or use coated diamond. Ultra fine metal powder and pre alloyed metal are suggested to use in the matrix for better bond performance. Process of powder granulation is promoted in producing segments to improve the distribution of diamonds in the segment, increase the efficiency of cold pressing, decrease the consumption of mould. Analysis and comparison are made on commonly used sintering furnaces, their advantages and disadvantages are pointed out. Diamond wire saws are getting wider use, HIP and HP welding are proposed for making the beads.更多还原
