摘要

本研究采用火花等离子烧结法成功制备了 B4C-TiB2 复合材料。首先，使用市售 TiB2 和自行合成的 TiB2 研究了 TiB2 源对 B4C-TiB2 复合材料的影响。随后，研究了 Si/B 共掺 B4C 对复合陶瓷的影响，并考察了样品的微观结构、弹性和机械性能。结果表明，与使用商业 TiB2 制成的样品相比，使用自制 TiB2 粉末制成的 B4C-TiB2 复合材料具有更高的相对密度和更理想的弹性和机械性能。自制的 TiB2 和 Si/B-B4C 复合材料在总体性能上有更大的改善。Si/B 共掺杂样品的弹性模量、维氏硬度和断裂韧性值分别为 493 GPa、30.09 ± 1.97 GPa 和 4.31 ± 0.74 MPa m1/2。此外，TiB2-B4C 复合材料的非晶化程度随 Si/B 共掺量的增加而降低。

Improving properties of boron carbide (B4C) with silicon doping and titanium diboride addition

In this research, B₄C-TiB₂ composites were successfully fabricated via the spark plasma sintering method. First, the TiB₂ source effect on the B₄C-TiB₂ composites was investigated using commercially available TiB₂ and in-house synthesized TiB₂. Subsequently, the effect of Si/B co-doped B₄C on composite ceramics was studied, followed by examining the samples' microstructure and elastic and mechanical properties. The results showed that B₄C-TiB₂ composites made with in-house TiB₂ powder obtained higher relative density and more desirable elastic and mechanical properties than samples made with commercial TiB₂. In-house TiB₂ and Si/B-B₄C composites provided more properties improvement overall. The elastic modulus, Vickers hardness, and fracture toughness values of Si/B co-doped samples were 493 GPa, 30.09 ± 1.97 GPa, and 4.31 ± 0.74 MPa m^1/2, respectively. Additionally, the amorphization of the TiB₂-B₄C composite decreased with Si/B co-doping.
