摘　　要：用金属粉末注射成型的方法制备高硬度合金剪刀,其喂料使用440型不锈钢粉末和PEG/PMMA复合粘结剂制成。前人对该问题的研究主要集中在440型不锈钢粉末的PIM成型方法上,而本文结果表明:通过精确控制粉末的烧结条件和热处理工艺,就可以获得硬度高、粉末分布均匀、碳化物球化良好的制品。The production of hairdressing scissors which are produced by a metal injection moulding route,using a 440 type hardenable stainless steel powder and a PEG/PMMA composite binder system has been investigated. Previous research has highlighted a number of problems associated with the PIM processing of 440 type stainless steels. However, the present study has ascertained that,with careful control of the sintering conditions ,a microstructure with finely distributed,spheroidal chromium carbide and high hardness could be attained following subsequent heat treatment.
