The production method of spray casting is characterized in that: in a short period of time, the molten metal liquid is sprayed into fine particles (10-500 μ m) through the atomization device, and the spray casting is piled on the predetermined deposition plate.

　　喷铸成型制程突出的特点，便是熔融金属液急速冷却凝固及雾化作用，使金属液中过饱和的相能够微细化并均匀分散，战胜了传统铸造制程中，因冷却速率较慢而产生的微观的偏析及安排粗大的现象。喷铸成型制程由金属液直接成型为固态的粗胚体，也战胜了粉末冶金制程中，繁琐多道次处理程序及其安排密实度欠安及粉末氧化严峻的问题，使得喷铸成型资料比粉末冶金资料具有低气孔隙和较好的性能。

　　The outstanding feature of spray casting process is the rapid cooling, solidification and atomization of molten metal, which makes the supersaturated phase in the molten metal fine and evenly dispersed, and overcomes the phenomenon of micro segregation and coarse arrangement caused by slow cooling rate in traditional casting process. In the spray casting process, the metal liquid is directly formed into solid coarse embryo, which overcomes the problems of the complex multi-step processing procedures and the poor density arrangement and the severe powder oxidation in the powder metallurgy process, making the spray casting data have lower porosity and better performance than the powder metallurgy data.

    

　　喷铸成型的长处有很多，如：高的堆积速率，（一般为0.25～1.7千克／秒）；形状可复杂化，可减少加工过程；合金的分配多样化，成分不受限制；粗胚体的密度较粉末冶金高，氧化物含量也较小等。

　　There are many advantages of spray casting, such as: high stacking rate (generally 0.25-1.7kg / s); complex shape, which can reduce the processing process; diversified distribution of alloy, unrestricted composition; high density of rough embryo compared with powder metallurgy, low oxide content, etc.

　　在喷铸成型制程中，金属液能够非常快速地冷却凝固并凝结为实体形状，使得传统铸造制程的微观偏析问题及粉末冶金制程中氧化的缺陷，得以战胜，而表现出优异的资料特性。

　　In the spray casting process, the liquid metal can cool and solidify very quickly and form solid shape, which makes the micro segregation problem in the traditional casting process and the oxidation defect in the powder metallurgy process overcome, and shows excellent data characteristics.

　　喷铸成型的制程方法是一种新型的铝合金成型方法，是建材、汽车部件、核电厂使用复合材等上佳挑选。

　　Spray casting process is a new type of aluminum alloy forming method, which is a good choice for building materials, auto parts, and composite materials used in nuclear power plants.
