Résumé | In the challenging market of powder metallurgy, part manufacturers must find ways to compete with other manufacturing techniques. Hence, the capability to produce high-strength parts is an interesting topic. Pressing to a higher density is a favoured method to achieve higher strength. Designing premixes with small amounts of organic additives is a practical way to improve compressibility. Lowering the lubricant content is possible if its lubricity is sufficient to prevent surface and/or tool damage. Warm die compaction is another common way to improve powder mix compressibility. In this paper, a new high-performance lubricant is introduced. Physical properties and surface finish were compared for mixes containing a common wax and the new developed lubricant. The ejection properties were also evaluated at temperatures of 60 °C, 80°C and 90 °C. It is shown that high densities with no surface deterioration can be obtained by using lower content of this high-performance lubricant. |
