Abstract
This study successfully introduced a pre-sintering process for the preparation of copper matrix composites and improved the combination of h-BN and the metal matrix. The effects of adding Mn and Ni in the pre-sintering of h-BN and their functionalization during pre-sintering were investigated. Our results show that h-BN was activated by introducing hydroxyl groups onto its surface after pre-sintering. A Mn3(BO3)2 glass phase was formed by the reaction between Mn and activated h-BN, which filled the pores via viscous flow and decreased the porosity of the composite. Furthermore, the addition of Ni reduced the pre-sintering reaction temperature. Thus, the relative density of the pre-sintered h-BN/CuSn10 composite was increased to 90.7% compared to that of the pristine original. The tensile strength and impact toughness of the former demonstrated significant improvement, by 26% and 168% respectively, to 156 MPa and 7.5 J/cm2, respectively.
