摘要

摘要: 通过正交试验法，以磨耗比、电阻、完整性、硬度为指标，设计了金刚石复合片的合成工艺。正交试验可以减少合成工艺试验次数，优化合成工艺。试验结果表明，较合理的烧结工艺为：合成压力5.5 GPa，升温速度为200 ℃/min，保温时间16 min，冷却时间14 min，烧结温度1 350 ℃。从压力、温度和时间等因素的影响方面讨论了金刚石复合片的性能。认为：适当地提高温度有利于提高磨耗比及硬度；延长加热时间有利于性能均匀性的提高；延长冷却时间可减少残余热应力。

Abstract: The wear ratio, resistance, integrality and hardness of polycrystalline diamond compacts (PDC) are investigated. The high pressure sintering processes are optimized using orthogonal experiments. According to our experimental results, the optimized parameters for the high pressure sintering of PDC are determined as below: pressure 5.5 GPa, temperature 1 350 ℃, temperature rising rate 200 ℃ /min, cooling time 14 min, and sintering time 16 min. It is found that the wear ratio and micro-hardness can be improved by increasing sintering temperature. The temperature distribution in the sample cell is reduced and PDC microstructure becomes more uniform by prolonging the heating time. The residual stress is also found to be decreased by prolonging the cooling time.
