Gradient layered B4C-TiB2/Al composite material and preparation method thereof
The invention provides a gradient layered B4C-TiB2/Al composite material and a preparation method thereof. The whole gradient layered B4C-TiB2/Al composite material is in a solid cylinder shape, metal and ceramic are in continuous gradient distribution in the radial direction and are in layered alternate distribution in the axial direction, the volume fraction of a B4C-TiB2 ceramic phase at the periphery part is 95-60 vol% and is reduced in a gradient mode from outside to inside, and the volume fraction of a metal phase is 5-40 vol%, and is increased in a gradient mode from outside to inside; the volume fraction of the B4C-TiB2 ceramic phase in the core part is 20-0 vol%, and the volume fraction of the metal phase in the core part is 80-100 vol%; the thickness of the ceramic layer is gradually transited from 100-50 microns to 10-0 microns from the periphery to the core part; and the thickness of the metal layer is gradually transited from 5-10 microns to 200-300 microns. The exterior of the composite material has high wear resistance, fatigue strength and bending strength, and the core part of the composite material has high plasticity and toughness.
本发明提出了一种梯度层状B4C‑TiB2/Al复合材料及其制备方法，整体为实心圆柱形，在径向金属与陶瓷呈连续梯度分布，在轴向呈层状相间分布，外围部分B4C‑TiB2陶瓷相所占的体积分数为95～60vol％，且从外向内梯度减少，金属相所占的体积分数为5～40vol％，且从外向内梯度增加；心部B4C‑TiB2陶瓷相所占的体积分数为20～0vol％，金属相所占的体积分数为80～100vol％；由外围至心部，陶瓷层的厚度由100～50μm逐渐过渡到10～0μm；金属层的厚度由5～10μm逐渐过渡到200～300μm。本发明复合材料外部具有高的耐磨性、疲劳强度和抗弯强度，心部具有高的塑韧性。
