Metal injection molding (MIM) is a combination of powder metallurgy and plastic injection molding technologies. This method consists of four main steps: preparation of feedstock, injection molding, debinding and sintering. In inserted metal injection molding (IMIM), the feedstock is injected on a preformed wrought insert to fabricate a multi-functional specimen. In the present work, the insert was made of 1050 carbon steel, coated by nickel (Ni) interlayers with thicknesses of 10, 20 and 30 μm, on which 316 L feedstock was injected. The injected specimens were debound, and then sintered at four different temperatures of 1260, 1300, 1340 and 1380 °C. The effects of sintering temperature and interlayer thickness on diffusion bonding were evaluated by shear strength measurement. As a result, the specimen sintered at 1300 °C with an interlayer having a thickness of 30 μm exhibited the highest shear strength of 238 MPa, while the lowest strength, 170 MPa, was achieved for specimen sintered at 1260 °C having no interlayer.

金属注射成型（MIM）是粉末冶金和塑料注射成型技术的结合。该方法包括四个主要步骤：原料的制备，注塑，脱脂和烧结。在插入式金属注射成型（IMIM）中，将原料注射到预制的锻件上以制造多功能样品。在本工作中，插入件由1050碳钢制成，并涂有厚度为10、20和30μm的镍（Ni）中间层，并在其上注入316 L原料。将注入的样品脱粘，然后在1260、1300、1340和1380°C的四个不同温度下烧结。通过剪切强度测量来评估烧结温度和中间层厚度对扩散结合的影响。结果是，
