摘　　要：开发研究了一种用于钛合金熔模精铸型壳面层的新型ＬＪ８型粘结剂；叙述了用该粘结剂制备型壳的工艺过程。用这种型壳所浇注出的钛铸件表面粗糙度为Ｒａ２６μｍ，污染层厚度为３０μｍ以下，实际浇注试验表明，所研制的新型粘结剂完全适用于钛合金熔模精密铸造。Abstract LJ8 new binder for primary slurry in titanium investment casting has been developed and the ceramic shell process using the binder was described.The surface roughness of the investment casting produced by this process is Ra 26μm,the thickness of contamination layer is less than 30μm.The result of pouring test showed that the new binder developed is suitable for titanium investment casting.
