Preparation method of boron carbide/diamond composite bulletproof material
The invention relates to a high-strength and high-toughness boron carbide diamond composite ceramic bulletproof sheet and a preparation method thereof, and belongs to the field of composite ceramic protection. Required materials comprise boron carbide, diamond, silicon, titanium and other sintering aids. The preparation method comprises the steps of material mixing, pressing, SPS sintering, grinding and polishing and detection. Wherein the proportion of the diamond is 10 to 30 wt%, the proportion of the boron carbide is 60 to 75 wt%, and the proportion of the sintering aid is 8 to 20 wt%; the particle size of the boron carbide is 2-4 [mu] m, and the particle size of the diamond is 1-45 [mu] m. The prepared boron carbide diamond composite ceramic chip is small in density, high in hardness and good in toughness. The surface of the diamond is graphitized at high temperature and reacts with silicon to generate silicon carbide, so that the compactness of a sample is better. The composite bulletproof ceramic prepared by the invention has greatly improved hardness, toughness and bending strength, is suitable for bulletproof field requirements, and has high application value.
本发明涉及一种高强高韧碳化硼金刚石复合陶瓷防弹片及其制备方法，属于复合陶瓷防护领域。所需材料为：碳化硼、金刚石、硅、钛等助烧剂，制备方法包括混料，压制，SPS烧结，打磨抛光，检测；其中，金刚石所占比例为10‑30 wt%，碳化硼所占比例为60‑75 wt%，助烧剂所占比例为8‑20 wt%；所述碳化硼粒径为2‑4 μm，所述金刚石粒径为1‑45 μm。所制备的碳化硼金刚石复合陶瓷片密度小、硬度高、韧性好。在高温下金刚石表面会有石墨化，与硅反应生成碳化硅，使样品致密性更好。本发明制备的复合防弹陶瓷硬度、韧性、抗弯强度都有较大提高，适用于防弹领域需求，具有较高的应用价值。
