| 摘 要： | 通过多金属电解法制备FeNiCo预合金粉末,采用X射线衍射仪和扫描电子显微镜对预合金粉末及其烧结体进行形貌观察和物相分析,研究FeNiCo预合金粉不同温度烧结时烧结体的力学性能和磨损性能,并探讨其在金刚石绳锯中应用的可行性。结果表明:制备的FeNiCo预合金粉一定程度上实现合金化,粉末呈不规则状,粒度较细;FeNiCo预合金粉在800~840℃烧结时,烧结体硬度最大值为107.6 HRB,三点抗弯强度最大值为1638.3MPa,致密度最大值为96.2%,磨损质量损失为0.498~0.555g,烧结温度适应性较好。采用FeNiCo预合金粉为主要胎体成分制作金刚石绳锯锯切硬质石材时,切割效率为8.6 m^2/h,工具寿命为11.3 m^2/m,具有较好的综合使用性能。
