摘要: 采用L9(34)正交试验研究未镀金刚石、表面镀Ti和镀Ni金刚石在不同强度结合剂下对金刚石工具出刃高度的影响,并使用SEM 3D重构法测量金刚石的出刃高度,对比分析不同状态下的金刚石出刃高度变化。结果表明:使用SEM 3D重构法能够方便、快速和准确地测量金刚石的出刃高度,高度值为221.26~321.68 μm;金刚石表面镀层和基体强度对金刚石出刃高度有明显影响,镀Ti金刚石的出刃高度大于镀Ni金刚石的,且二者均大于未镀金刚石的。Abstract: The effects of uncoated diamond, Ti-coated and Ni-coated diamond with different bond strength on the protrusion height of diamond tool was studied through L9(34) orthogonal experiments. The SEM 3D reconstruction method was used to measure the protrusion height of diamond particles. The protrusion height of different diamonds particles were compared and analyzed. The results show that the protrusion height of diamond particles can be measured conveniently and quickly by using SEM 3D reconstruction method, the protrusion height is 221.26~321.68 μm; and the coating on the diamond surface and bond strength of diamond bits have both apparent effect on the protrusion height of diamonds particles. Moreover, the protrusion height of Ti-coated diamond is higher than that of Ni-coated diamond, and both of them are larger than that of uncoated diamond.
