The effect of TiN source (i.e., TiN powder, TiO2 powder and TiO2 sol) on the phase compositions, microstructures and mechanical properties of hot-pressed Si3N4-TiN ceramics was investigated. The results show that only β-Si3N4 and TiN phases are detected for the sample with TiN powder. The sizes of β-Si3N4 and TiN grains are large, the Vickers hardness, flexure strength, and fracture toughness are (15.6±0.3) GPa, (1 058±78) MPa, and (11.2±0.6) MPa·m1/2, respectively. However, the O′-Sialon phase appears in the sample with TiO2 powder in addition to β-Si3N4 and TiN phases, and the content of O′-Sialon is 8.7wt%. Due to the relatively fine grains of β-Si3N4 and TiN, the Vickers hardness increases to (16.7±0.4) GPa, and the flexure strength and fracture toughness are (986±76) MPa and (11.3±0.4) MPa·m1/2, respectively. Moreover, the O′-Sialon phase appears in the sample with TiO2 sol, the content of O′-Sialon is 12.5wt%, and the size of β-Si3N4 and TiN grains is finer, having a higher Vickers hardness (i.e., 16.6±0.5 GPa), and relatively lower flexure strength (i.e., 788±94 MPa) and fracture toughness (i.e., 10.2±1.0 MPa·m1/2). Si3N4-TiN ceramics with uniformly fine microstructures and good mechanical properties can be thus obtained with TiO2 powder.

研究了TiN的来源(TiN粉、TiO2粉和TiO2溶胶)对热压烧结Si3N4-TiN复相陶瓷的相组成、显微结构与力学性能的影响。结果表明,当以TiN粉为第二相添加剂时,试样中仅检测到β-Si3N4和TiN相,Si3N4晶粒与TiN颗粒较粗大,硬度、强度和断裂韧性分别为(15.6±0.3)GPa、(1 058±78)MPa和(11.2±0.6)MPa·m1/2;当以TiO2粉为第二相添加剂时,除了β-Si3N4和TiN相,还检测到O′-Sialon相,O′-Sialon相的含量为8.7%(质量分数),Si3N4晶粒与TiN颗粒均匀细小,样品硬度提高到(16.7±0.4)GPa,强度和断裂韧性没有显著变化,分别为(986±76)MPa和(11.3±0.4)MPa·m1/2;当以TiO2溶胶为第二相添加剂时,同样检测到O′-Sialon相,O′-Sialon相的含量为12.5%,Si3N4晶粒与TiN颗粒均匀细小,样品硬度较高为(16.6±0.5)GPa,其强度和断裂韧性较低分别为(788±94)MPa和(10.2±1.0)MPa·m1/2。以TiO2粉为第二相添加剂时,可获得显微结构均匀细化、综合力学性能较佳的Si3N4-TiN复相陶瓷材料。

研究了TiN的来源(TiN粉、TiO2粉和TiO2溶胶)对热压烧结Si3N4-TiN复相陶瓷的相组成、显微结构与力学性能的影响。结果表明,当以TiN粉为第二相添加剂时,试样中仅检测到β-Si3N4和TiN相,Si3N4晶粒与TiN颗粒较粗大,硬度、强度和断裂韧性分别为(15.6±0.3)GPa、(1 058±78)MPa和(11.2±0.6)MPa·m1/2;当以TiO2粉为第二相添加剂时,除了β-Si3N4和TiN相,还检测到O′-Sialon相,O′-Sialon相的含量为8.7%(质量分数),Si3N4晶粒与TiN颗粒均匀细小,样品硬度提高到(16.7±0.4)GPa,强度和断裂韧性没有显著变化,分别为(986±76)MPa和(11.3±0.4)MPa·m1/2;当以TiO2溶胶为第二相添加剂时,同样检测到O′-Sialon相,O′-Sialon相的含量为12.5%,Si3N4晶粒与TiN颗粒均匀细小,样品硬度较高为(16.6±0.5)GPa,其强度和断裂韧性较低分别为(788±94)MPa和(10.2±1.0)MPa·m1/2。以TiO2粉为第二相添加剂时,可获得显微结构均匀细化、综合力学性能较佳的Si3N4-TiN复相陶瓷材料。

The effect of TiN source (i.e., TiN powder, TiO2 powder and TiO2 sol) on the phase compositions, microstructures and mechanical properties of hot-pressed Si3N4-TiN ceramics was investigated. The results show that only β-Si3N4 and TiN phases are detected for the sample with TiN powder. The sizes of β-Si3N4 and TiN grains are large, the Vickers hardness, flexure strength, and fracture toughness are (15.6±0.3) GPa, (1 058±78) MPa, and (11.2±0.6) MPa·m1/2, respectively. However, the O′-Sialon phase appears in the sample with TiO2 powder in addition to β-Si3N4 and TiN phases, and the content of O′-Sialon is 8.7wt%. Due to the relatively fine grains of β-Si3N4 and TiN, the Vickers hardness increases to (16.7±0.4) GPa, and the flexure strength and fracture toughness are (986±76) MPa and (11.3±0.4) MPa·m1/2, respectively. Moreover, the O′-Sialon phase appears in the sample with TiO2 sol, the content of O′-Sialon is 12.5wt%, and the size of β-Si3N4 and TiN grains is finer, having a higher Vickers hardness (i.e., 16.6±0.5 GPa), and relatively lower flexure strength (i.e., 788±94 MPa) and fracture toughness (i.e., 10.2±1.0 MPa·m1/2). Si3N4-TiN ceramics with uniformly fine microstructures and good mechanical properties can be thus obtained with TiO2 powder.
