Description
技术领域
本发明涉及一种陶瓷喷嘴制备工艺，属于喷嘴成型技术领域，具体涉及一种氧化铝/氧化锆复合的陶瓷喷嘴及其制作方法。
背景技术
陶瓷喷嘴自上个世纪九时年代引入中国以来，材料不断的改进更新，从氧化物陶瓷逐渐发展到氮化物陶瓷和碳化物陶瓷，而生产工艺及制备方法落后，致使现有技术中陶瓷喷嘴存在诸多缺陷，比如硬度不高、耐磨性差、防腐蚀防冲蚀能力弱、延展性不大等。为克服现有技术的不足，有必要对现有陶瓷喷嘴生产技术加以改进，从而制得适合不同需求的具有成本低、功能多元化、阻燃、硬度高、耐磨、防辐射等功能的陶瓷喷嘴。
发明内容
本发明的目的就是提供一种氧化铝/氧化锆复合的陶瓷喷嘴及其制作方法，以克服现有技术的不足。
