用水雾化法制造金刚石工具用 FeCu 合金粉末，通过对雾化工艺、还原工艺的优化设计，对不同还原温度制得的粉末检测其松比、氧含量的变化，结合金刚石工具的胎体硬度、抗弯强度与切割效率、耐磨性、切割寿命之间的关系，研制性能优良，用途广泛的合金粉末。试验结果表明：雾化水压力80 M Pa ，水流量80 L ／min ，选用5 mm 漏嘴，还原温度在（600±10）℃，还原时间25 min 时，制得的合金粉末各项性能指标最佳。

FeCu alloy powder , which was used to make diamond tools , was prepared using water atomization method . Both atomizing and reducing processes were optimized . Powder prepared at different temperatures were tested on their loose ratios and oxygen contents , which could help to prepare new powder with better property and wider application considering matrix hardness , bending strength , cutting efficiency , wear resistance , and cutting life . Results showed that the powder possessed best property when prepared at atomizing pressure 80 M Pa , water flow 80 L/ min , and reducing temperature (600 ± 10) ℃ for 25 minutes and with a nozzle of 5 mm .
