研究了一种以ＰＥＧ为主要组分的粘结剂， 考察了它对Ｆｅ－ ２Ｎｉ 粉末注射成形的适应性．实验结果表明： 该粘结剂体系混合和注射工艺性能好， φ（Ｆｅ－ ２Ｎｉ） 粉末装载量可达５５ ％ ，水中脱脂速度可达０ ．８ ～２ ｍｍ／ｈ．
A binder based on PEG was investigated and its suitability for Fe-2Ni powder injection molding was investigated. The experimental results show that the binder system has good mixing and injection process performance, the loading capacity of φ (Fe-2Ni) powder can reach 55%, and the degreasing speed in water can reach 0. 8 ~ 2 mm / h.
