Abstract
Generally, metal injection molding (MIM) process has been utilized for mass production of complicated and near net shape parts using single material. If plural materials are joined in MIM process, multi-functional compacts can be manufactured in high productivity and high quality. Joining of stainless steels (SUS316L/SUS430L) by using insert injection molding was reported in our previous paper.
In this study, several hard materials were selected to join with stainless steels (SUS316L) by using insert injection molding. Especially, the combination of SUS316L and SUS420J2 showed good joining because of the diffusion of Ni and Mo from SUS316L to SUS420J2.
