摘要
胎体对金刚石工具性能的影响至关重要,热压温度、压力和时间的变化显著影响金刚石胎体的性能。采用SEM、EDS、硬度检测及弯曲试验等分析测试方法,研究了热压工艺参数对含磷铁基胎体(Fe-Cu-P三元胎体)组织性能的影响。综合分析了胎体的各项性能及实验参数,确定胎体的最佳烧结温度为820℃,最佳烧结压力为30 k N,最佳烧结时间为270 s。
The diamond matrix is very important to the performance of diamond tool,and the processing parameters has a significant impact on the performance of diamond matrix. The variable control method was adopted in this paper. The effects of sintering process parameters on the microstructure and property of the Fe-Cu-P ternary matrix were studied by taking sintering temperature,time and pressure as single variables. The properties of the matrix and the experimental parameters were comprehensively analyzed. The 820 ℃,30 kN,and 270 s were chosen as the best sintering temperature,pressure,and the optimum time,respectively.
