摘　　要：为了改进金刚石微粉烧结体的机械性能,利用现有的激光技术,采用高功率横流CO2激光烧结金刚石微粉压坯,研究在不同的激光工艺参数下,烧结体中的金刚石微粉与金属粉末粘结的结合性能、微观结构以及形成机理。结果表明,在合适的激光工艺参数下可以得到组织结构良好的金刚石微粉压坯烧结体,显著提高烧结体的致密性和耐磨性,开辟了一种金刚石工具制造的新工艺。In order to improve diamond fine powder sinter＇s mechanical property, using the present laser technique, high power transverse CO2 laser is used to sinter diamond fine powder compact to study the integrating capability in the sinter between diamond fine powder and metallic powder, microstructure and the forming mechanism of microstructure in the different laser technical parameters. The results show that the fine sintering will be gained in the reasonable laser technical parameter,which can improve densenses and wear resistance,inaugurate a new technique of manufacture diamond tools.
