摘要: 为了研究钛对铝基结合剂金刚石节块把持力的影响,在铝基结合剂中添加不同质量分数的钛,用热压法烧结得到不含和含金刚石的铝基结合剂节块,测试添加不同质量分数钛时,金刚石节块的抗弯强度,计算铝基结合剂对金刚石的把持力系数,并用扫描电子显微镜和能谱分析仪对铝基结合剂金刚石节块的断口微观形貌和成分进行分析。结果表明:随着钛质量分数的增加,不含和含金刚石的铝基结合剂节块的抗弯强度和把持力系数有相同的变化趋势,都是先增大再减小。在添加质量分数3%钛时,铝基结合剂金刚石节块的抗弯强度最大,其值为145 MPa,相应的把持力系数为82.5%,此时铝基结合剂与金刚石间结合最好。Abstract: To study the effect of Ti on the holding force of Al-based bonded diamond bits, Ti powders in different mass fractions were added in the Al-based bonded, the Al-based bonded bits without and with diamond were fabricated by hot pressing method. The flexural strength of bits with different Ti contents by mass were tested, and the holding force coefficient between Al-based bonded and diamond were calculated. Moreover, the fracture surface morphology and composition of the Al-based bonded diamond bits were characterized by scanning electron microscope and energy dispersive X-ray micro-analyzer. The results show that, with the increasing of Ti content by mass, the flexural strength and holding force coefficient of the bits are enhanced firstly and then decreased. When the adding content of Ti powder is 3% by mass, the maximum values of flexural strength and holding force coefficient are 145 MPa and 82.5 %, respectively; furthermore, the combining state between Al-based bonded and diamond is the best.
