Organic-bonded powders : A cost effective alternative to diffusion- alloyed powders
A large proportion of high-performance Mo-Ni-Cu steel parts is produced from diffusion-alloyed powders, which offer unique properties and a greater compositional consistency compared to standard mixes. However, the rising price of alloying elements combined with the cost of manufacturing, make these powders less attractive. Only a few standard grades are available and it is almost impossible to make minor compositional adjustments due to the nature of the process. The FLOMET organic-bonding process is a cost effective route that like the diffusion-alloyed process, ensures excellent Ni and Cu bonding. This process offers several advantages: better compressibility, high versatility: it is easy to make chemical compositional adjustments and/or change additive grades to optimize properties and cost, better flow rate and reduced graphite dusting. Organic-bonded powders are seen as a cost effective alternative to diffusion-alloyed powders for producing high-performance parts. In this paper, properties and characteristics of organic-bonded Mo-steel powders containing Cu and Ni are presented and compared to those of diffusion-alloyed grades. Particular attention is paid to the influence of composition and selection of additive grades on powder and part properties together with cost considerations.
