Description
技术领域
本发明涉及陶瓷喷嘴技术领域，具体是一种高韧性陶瓷喷嘴材料及其制备方法。
背景技术
非晶磁环是用非晶材料加工的磁性元件。根据所用非晶带材的材质不同，可分为铁基非晶，钴基非晶等等。根据材料的形状，可分为带材型磁环和粉末型磁环。非晶磁环的特点的饱和磁密远高于普通铁氧体和粉末磁芯。非晶磁环或称为金属玻璃，它是20世纪70年代问世的一种新型材料，是利用急冷技术将钢液一次成型为厚度为30微米的薄带，然后通过薄带绕制而成。
在非晶磁环加工过程中，喷嘴是关键部件，熔融状态的合金从喷嘴的狭缝中喷出，被移动的冷却基质快速冷却凝固，从而生产出连续的非晶带材。由于喷嘴的工作条件苛刻，要求抗瞬时热震、抗高速气流冲击、抗高温熔融金属的冲刷、耐化学腐蚀以及抗氧化。现有的陶瓷喷嘴材料普遍存在韧性不足、使用寿命短的缺陷，难以满足市场对喷嘴性能日益提高的需求。
