| Résumé | Mo-Ni-Cu steel powders are widely used to manufacture high performance PM parts. A large proportion of these parts are produced from diffusion-alloyed powders, where Ni and Cu are partially diffused with steel powder to enhance bonding and chemical consistency. Binder-treatment technology such as the FLOMET™ process is a cost effective alternative to the diffusion-alloyed process that also ensures excellent Ni and Cu bonding. Recent developments in the FLOMET process have allowed the development of new Organic-Bonded powders offering Ni and Cu bonding strength similar to that of diffusion-bonded powders but with improved compressibility and chemical versatility. The compaction and ejection behaviour as well as the dusting resistance of Mo-Ni-Cu steel powder mixes produced with diffusion-alloyed, organic-bonded and conventional mixing were evaluated on an industrial press. The dusting resistance of each mix was determined by measuring the amount of dust (Ni, Cu, Fe and others) around the die cavity and on the press operator. The chemical and dimensional consistency of parts sintered in a fast cooling industrial furnace is also discussed. |
