| Abstract |
The SKD11 powder was used to fabricate the components by the metal injection molding (MIM) process. The effects of sintering parameters, powder vendors, particles size and binders on the microstructure and mechanical properties of sintered components were analyzed in this study. Experimental results revealed the hardness and wear-resistance increased with an increase of sintering time. The powder fabrication by gas-atomization process was harder than those of water-atomization after sintered. A smaller particle size had superior microstructure, hardness and wear-resistance performance after sintered; however, dramatic fluctuations of friction force was observed in the specimen. The effect of binders to the mechanical properties of sintered parts was not apparent in this study. Addition of 10 wt.% iron powder to the SKD11 powder increases the hardness of sintered part, as well as reduceing the cost of powder. |
