Although engineering ceramics are widely used in industry, its high brittleness is one of the main factors restricting its popularization. This paper was to synergistically improve the strength and toughness of engineering structural ceramics. A wood tree ring-like Si3N4/Ni composite was prepared with micron-sized powder of Si3N4 and high purity nickel wire via hot pressing sintering. The interface bonding between Si3N4 matrix and Ni wire in Si3N4/Ni composite was investigated, and the physical and mechanical properties of the composite were characterized. The results show that the interface between Si3N4 matrix and Ni wire in the composite is well bonded, and the wood tree ring-like material structure contributes to the strengthening and toughening of ceramic materials. The bending strength and fracture toughness of the composite are (989±87) MPa and (8.12±0.8) MPa·m1/2, respectively. Compared with single-phase Si3N4, the physical and mechanical properties of Si3N4 ceramics are improved.

工程陶瓷已广泛应用于工业领域,而其较高的脆性一直是推广受限的主要因素之一。基于此,本研究旨在协同提高工程结构陶瓷的强度和韧性。以微米级Si3N4粉体和高纯度镍丝为原料,借鉴仿生制备思路,利用热压烧结的方式制备仿木质年轮状Si3N4/Ni复合材料,研究了Si3N4/Ni复合材料中Si3N4与Ni丝的界面结合状态,测试了复合材料的物理力学性能。结果表明,复合材料中Si3N4基体与Ni之间界面结合良好,仿木质年轮的材料结构有助于陶瓷材料的强韧化,复合材料的弯曲强度达(989±87) MPa,断裂韧性达(8.12±0.8) MPa·m1/2,较单相Si3N4陶瓷的物理力学性能有较好的提升。

工程陶瓷已广泛应用于工业领域,而其较高的脆性一直是推广受限的主要因素之一。基于此,本研究旨在协同提高工程结构陶瓷的强度和韧性。以微米级Si3N4粉体和高纯度镍丝为原料,借鉴仿生制备思路,利用热压烧结的方式制备仿木质年轮状Si3N4/Ni复合材料,研究了Si3N4/Ni复合材料中Si3N4与Ni丝的界面结合状态,测试了复合材料的物理力学性能。结果表明,复合材料中Si3N4基体与Ni之间界面结合良好,仿木质年轮的材料结构有助于陶瓷材料的强韧化,复合材料的弯曲强度达(989±87) MPa,断裂韧性达(8.12±0.8) MPa·m1/2,较单相Si3N4陶瓷的物理力学性能有较好的提升。

Although engineering ceramics are widely used in industry, its high brittleness is one of the main factors restricting its popularization. This paper was to synergistically improve the strength and toughness of engineering structural ceramics. A wood tree ring-like Si3N4/Ni composite was prepared with micron-sized powder of Si3N4 and high purity nickel wire via hot pressing sintering. The interface bonding between Si3N4 matrix and Ni wire in Si3N4/Ni composite was investigated, and the physical and mechanical properties of the composite were characterized. The results show that the interface between Si3N4 matrix and Ni wire in the composite is well bonded, and the wood tree ring-like material structure contributes to the strengthening and toughening of ceramic materials. The bending strength and fracture toughness of the composite are (989±87) MPa and (8.12±0.8) MPa·m1/2, respectively. Compared with single-phase Si3N4, the physical and mechanical properties of Si3N4 ceramics are improved.
