Self-lubricating ceramic cutter with self-repairing capability as well as preparation method, repairing method and application of self-lubricating ceramic cutter
The invention relates to the technical field of self-repairing cutters, in particular to a self-lubricating ceramic cutter with self-repairing capacity as well as a preparation method, a repairing method and application of the self-lubricating ceramic cutter. The ceramic cutter is prepared from the following components: 55 to 64 percent of alpha-Al2O3; 22 to 28 percent of TiC; 5 to 10 percent of TiB2; 5 to 10 percent of h-BN@Al2O3 and 0.5 percent of MgO, wherein the h-BN@Al2O3 is of a core-shell structure formed by coating flaky nano h-BN with Al2O3. In the ceramic cutter, the TiB2 is used asa repairing agent; the h-BN@Al2O3 is used as a solid lubricant and a repairing agent; the Al2O3 is used as a matrix; the TiC is used as a reinforcing phase; the MgO is used as a sintering aid; and under the synergistic effect of the TiB2 and the h-BN@Al2O3, the crack repairing effect and the self-lubricating capacity of the material of the cutter are improved, and the comprehensive mechanical property of the material of the cutter is enhanced.
本发明涉及自修复刀具技术领域，尤其涉及一种具有自修复能力的自润滑陶瓷刀具及其制备方法、修复方法与应用。按体积百分数计，所述陶瓷刀具包括如下组分：α‑AlO55‑64％，TiC 22‑28％，TiB5‑10％，h‑BN@AlO5‑10％，MgO 0.5％；所述h‑BN@AlO是以AlO包覆在片状纳米h‑BN上形成的核壳结构。该陶瓷刀具中以TiB为修复剂，h‑BN@AlO为固体润滑剂兼修复剂，AlO为基体，TiC为增强相，MgO为烧结助剂，在TiB和h‑BN@AlO的协同作用下提高了刀具材料的裂纹修复效果和自润滑能力，增强了刀具材料的综合力学性能。
