Manufacturing method of particles for manufacturing toughened ceramic
The invention discloses a manufacturing method of particles for manufacturing toughened ceramic, and is characterized in that a ceramic phase and a second toughening phase are subjected to co-extrusion treatment in the particle manufacturing process to form a core-shell coating structure taking a ceramic phase matrix as a shell and taking the second toughening phase as an inner core. The beneficial effect of the invention is that the composite particles have good wear resistance and good toughness. The fracture toughness is improved to 9.0 MPa*m<1/2> from traditional 3-5 MPa*m<1/2>.
本发明公开了一种增韧陶瓷制作用颗粒的制作方法，其特征在于，在制做颗粒过程中将陶瓷相和增韧第二相共挤压处理，形成陶瓷相基体为外壳、增韧第二相为内核的核壳包覆结构。本发明的有益效果为：其既具有较好的耐磨性也具有较好的韧性。断裂韧性由传统的3‑5MPa∙m提高至9.0 MPa∙m。
