这一幕太解气!中国700℃自愈合金问世,西方连夜放宽出口限制!
Sou Hu Cai Jing· 2025-08-20 12:32
上世纪70年代,当中国工程师想研究涡轮盘样品时,西方国家不仅拒绝提供,甚至放言:"他们造不出会飞的发动机"。 航空工业的 "心脏起搏器":高温合金涡轮盘的前世今生 在飞机发动机里,有一个看似不起眼却至关重要的零件——高温合金涡轮盘。这个直径不到半米的金属圆盘,每分钟转速超过1万转,承受着700℃以上的高 温和相当于汽车轮胎气压200倍的应力。 一块直径1米的金属圆盘问世,长期对华禁运高温合金的某西方国家突然表示"考虑放宽出口限制"。 这种技术封锁源于高温合金的特殊属性。制造涡轮盘的镍基合金需要添加十几种稀有金属,通过精密铸造和热处理工艺形成定向晶或单晶结构,才能在极端 环境下保持稳定性。 美国从上世纪50年代开始研发,直到80年代才实现工业化生产,长期将相关技术列为"绝对机密"。中国早期只能依赖进口,不仅价格昂贵(每吨超过百万 元),而且交货周期长达数年,严重制约了国产大飞机和先进战机的研发进度。 30年磨一剑 面对西方的技术壁垒,中国科研人员选择了自主创新的艰难道路。从2000年开始,北京航空航天大学、西北工业大学等高校联合中航工业集团,启动了"高 温合金涡轮盘国产化"攻关项目。 他们首先在材料配方上取得突 ...
