摘要
本文叙述了采用金属面层陶瓷型壳工艺,研制大型薄壁壳体类钛合金精密铸件。采用合适的工艺和离心浇注方法,获得了尺寸精确、表面光洁的铸件;采用热等静压处理,消除了铸件的内部缺陷,满足了承受高工作压力的要求,铸件作为重要结构件已获得应用。
This paper describes the research and manufacture of titanium investment casting for large sized housing type structure of thin wall using the ceramic shell with metal face layer.The casting of precision demension and adequate surface finish are obtained by proper process and centrifugal pouring.In order to meet the requirements of bearing the high working pressure, the internal defects are removed by hot isostatic pressing treatment.This titanium cast-ing.as an important structure.has been used in the air-space industry already.
