摘要
通过型壳试样的湿强度、焙烧后强度、透气性的试验研究,分析了3种不同背层制壳工艺的型壳性能;应用3种制壳工艺生产厚壁复杂结构钛合金铸件,确定了碳纤维制壳工艺为最适合批量生产厚大复杂结构钛合金精铸件加固层型壳的工艺。
The performances of shells by three different shell making processes are analyzed through studying wet strength,fired strength and permeability of specimens.Titanium alloy castings with complex structures have been produced by the above proces-ses.among which,carbon fiber shell making process is the most suitable for mass production of reinforced layer shell of titanium alloy precision castings with complex structures.
