A metal-ceramic composite Cu-(LaB₆-TiB₂) has been produced by the spark plasma sintering. The microstructure, phase composition, mechanical properties and resistivity of the composite are studied. An effective method for reinforcing the interface between the copper matrix and reinforced ceramic particles LaB₆-TiB₂ has been proposed and implemented. It is demonstrated that consolidation of the metal-ceramic composite by using LaB₆-TiB₂ particles with naked fibers almost doubles the material's strength. Furthermore, the use of reinforced ceramic particles provides the electrical conductivity on a level with the best materials for resistance-welding electrodes (88% IACS).

Cu-（LaB 6 -TiB 2）金属陶瓷复合材料的放电等离子体烧结及其物理力学性能

通过火花等离子体烧结制备了金属陶瓷复合材料Cu-（LaB ₆ -TiB ₂）。研究了复合材料的微观结构，相组成，力学性能和电阻率。已经提出并实施了一种有效的方法来增强铜基体和增强陶瓷颗粒LaB ₆ -TiB ₂之间的界面。结果表明，使用裸露的LaB ₆ -TiB ₂颗粒固结金属陶瓷复合材料几乎会使材料的强度提高一倍。此外，增强陶瓷颗粒的使用可提供与用于电阻焊电极的最佳材料（88％IACS）水平相当的电导率。
