Abstract
本发明提供了一种钛合金防弹板及其制备方法，以钛合金板为基体，先对基体迎弹面和背弹面均进行喷砂粗化处理、浮尘清理、清洗、烘干；再在迎弹面和背弹面之上分别喷涂制备Ti/Al过渡层，喷涂完成后进行真空热处理；再在每个Ti/Al过渡层之上分别喷涂制备陶瓷层，喷涂完成后，进行真空热处理。本发明以钛合金板为基体，并将其迎弹面和背弹面均陶瓷化，迎弹面陶瓷化使得钛合金板具备了陶瓷的高强度，大大提升迎弹面对弹丸的破坏作用，从而提升防弹能力；背弹面陶瓷化，则增加了钛合金板的刚性约束，提升了钛合金板变形的吸能能力，从而进一步提高钛合金板的防弹能力。
Description
技术领域
本发明涉及材料表面改性技术领域，尤其是涉及一种钛合金防弹板及其制备方法。
背景技术
钛合金具有高的强度和韧性，且密度较低，在提高复合装甲防弹性能、减轻复合装甲的重量方面具有重要的应用。然而随着子弹侵彻能力越来越强，复合装甲中各结构材料的比重相应增大，降低了装备的机动性。
提高钛合金防弹能力的方法多为通过热处理方式提高其力学性能，试验发现，其防护能力提高甚微。其次是通过增大钛合金的厚度，但重量的增大降低了装备机动性。
涂层技术在表面防护领域一直受到推崇。热喷涂技术是制备涂层的关键技术之一，它利用热源将材料加热到熔化或半熔化状态，再经过高速气流或焰流使其雾化，加速喷射在材料表面，使其得到强化或改性，目前已在隔热、耐磨、耐腐蚀、减摩等领域得到广泛应用。
发明内容
有鉴于此，本发明提出一种钛合金防弹板及其制备方法，以钛合金为基体，在钛合金迎弹面和背弹面制备高性能涂层，实现钛合金表面陶瓷化，增大对弹丸的磨蚀作用和侵彻阻力，提高了钛合金防弹板的防弹能力，涂层的可设计程度高。
具体为：
一种钛合金防弹板的制备方法，其特征在于，以钛合金板为基体，包括：
步骤一：对钛合金板的迎弹面和背弹面均进行喷砂粗化处理；
步骤二：对喷砂粗化处理后的钛合金板基体进行表面浮尘清理，清洗表面，烘干；
步骤三：在钛合金板的迎弹面之上和背弹面之上分别喷涂制备Ti/Al过渡层，喷涂完成后进行真空热处理；
步骤四：在迎弹面和背弹面的Ti/Al过渡层之上分别喷涂制备陶瓷层，喷涂完成后，进行真空热处理。
进一步，Ti/Al过渡层通过超音速火焰喷涂法喷涂Ti/Al复合粉制备。
进一步，所述陶瓷层采用等离子喷涂法喷涂TiCN粉制备。
进一步，钛合金板厚度为1～5mm。
进一步，每个Ti/Al过渡层的厚度为80～100μm。
进一步，步骤三中Ti/Al过渡层进行真空热处理的工艺条件为：温度为500～800℃，保温时间为1～2h。
进一步，步骤四中陶瓷层进行真空真空热处理的工艺条件为：温度为300～400℃，保温时间为1～2h。
钛合金防弹板，以钛合金板为基体，在基体的迎弹面和背弹面分别依次叠加制备Ti/Al过渡层和TiCN陶瓷层。
本发明以钛合金板为基体，并将其迎弹面和背弹面均陶瓷化，迎弹面陶瓷化使得钛合金板具备了陶瓷的高强度，大大提升迎弹面对弹丸的破坏作用，从而提升防弹能力；背弹面陶瓷化，则增加了钛合金板的刚性约束，提升了钛合金板变形的吸能能力，从而进一步提高钛合金板的防弹能力。
附图说明
