摘要: 

采用球磨法制备了4种不同Ni含量的Cu-10Sn-xNi (x=15、30、45和60,质量分数,%)预合金粉末,分别经820、850和880 ℃热压烧结制备成合金块材,对预合金粉末和合金块材的微观组织和机械性能进行表征与检测。结果表明:球磨法制备的预合金粉末中出现了Cu3.8Ni相,当Ni含量增加到60%时,还出现了Ni3Sn相和非晶相。随Ni含量的增加和烧结温度的升高,烧结合金中Sn元素的偏析现象得到有效抑制,组织均匀性显著提高,同时合金的密度、抗弯强度和弯曲弹性模量均相应提升。但增加Ni含量对合金的硬度影响不大。880 ℃热压烧结制备的Cu-10Sn-60Ni合金具有最佳的综合性能,其硬度、抗弯强度和弯曲弹性模量分别100 HRB、1308 MPa和75.6 GPa。

Abstract

Diamond tools are widely used in industry. Co is considered as the best matrix for the diamond tools due to its excellent retention of diamond grits and flexible control of wear resistance. But its application is suppressed because of its high price. The rapidly increasing contribution of matrices to tool production costs continues to encourage researchers to find and implement cheaper alternatives. Cu-based alloys are ideal materials to replace Co used as diamond tool matrices because of their low sintering temperature, good formability and low price. However, Cu-based matrices can not effectively hold the diamonds due to their low mechanical strength and small elastic modulus, so the service life and processing efficiency of Cu-based diamond tools are difficult to be satisfied. In this work, four kinds of Cu-10Sn-xNi pre-alloyed powders with different Ni contents (x=15, 30, 45 and 60, mass fraction, %) were prepared by ball milling. Bulk samples were fabricated from the pre-alloyed powders by hot pressing sintering at 820, 850 and 880 ℃, respectively. The microstructures and mechanical properties of pre-alloyed powders and bulks were characterized and tested. The results show that Cu3.8Ni phase is detected in the pre-alloyed powders prepared by ball milling. For the powder with 60%Ni, Ni3Sn phase and amorphous phase are detected. With increasing the Ni content as well as the sintering temperature, the segregation of Sn element in sintered alloys is effectively suppressed and the microstructure becomes homogeneous significantly, and the density, flexural strength and flexural modulus of the alloys are correspondingly improved. However, increasing the Ni content has little effect on the hardness of the alloys. The Cu-10Sn-60Ni alloy prepared by hot pressing at 880 ℃ has the best comprehensive performance. Its hardness, flexural strength and flexural modulus are 100 HRB, 1308 MPa and 75.6 GPa, respectively.
