采用非匀相沉淀法制备纳米Al2O3包裹Al复合粉体,通过热压烧结制备出Al2O3/Al复合材料,利用差热分析仪、SEM、教显维氏硬度计及万能试验机测试研究了复合材料的微观结构及热力学性能.结果表明,经1 050℃/30 min煅烧岳获得的复合粉体成分为α-Al2O3和Al;同单相Al2O3相比,纳米Al的添加降低了瓷体的烧结温度;添加Al的摩尔数分数为10%的Al2O3/Al复合陶瓷的抗弯强度提高10%,断裂韧性提高了86%,硬度值随Al的增加而下降.

The nano-Al2O3-coated Al composite powder was prepared by heterogeneous precipitation, and Al2O3/Al composites were prepared by hot pressing sintering, and the microstructure and thermodynamic properties of the composites were studied by differential thermal analyzer, SEM, Jiaxian Vickers hardness tester and universal testing machine. The results showed that the compound powder components obtained by calcination at 1 050°C/30 min were α-Al2O3 and Al. Compared with single-phase Al2O3, the addition of nano-Al reduced the sintering temperature of porcelain. The flexural strength of Al10O2/Al composite ceramics with a molar fraction of 3% Al increased by 10%, the fracture toughness increased by 86%, and the hardness value decreased with the increase of Al.
