AbstractThe number of complex PM parts for high performance appilcation continuously increases. Compaction is one of the key processes to reach such high performances and lubricants play a key role in that regard. This explains in the significant level of efforts, in the last 20 years, devoted to the development of PM lubricants to improve both the processing and performances of PM parts (density, ejection, robustness, productivity, etc...). FOr instance, warm pressing, high green strength, high density as well as flow enhanced formulations were - and still are - being developed. The development of these lubricants requires the understanding of the lubrication mechanisms of these organic organometallic compounds. In this paper, the effect of different compacting processing parameters (pressure, temperature, compaction speed) on the lubrication behaviour of iron-based powder mixes compacted on either an instrumented laboratory press or an industrial mechanical press will be reviewed and presented as a function of different families of PM lubricants (conventional, High Density, High green strength, warm die (50-80ºC) and warm pressing (100-150ºC)).
