This work reports on the use of plasma technology in lubricant removal and sintering of compacted PM components. Unalloyed iron samples were treated in a hydrogen and argon discharge at a pressure of 400 Pa (3 Torr), varying the temperature and soaking time. The discharge was generated in a confined cathode-anode configuration with the sample placed on the anode. Samples were characterized by mass loss and the results were correlated with the plasma parameters. Approximately 80% of zinc stearate was removed using a H-2 discharge at 350degreesC during 5 minutes reaching 93% as the time was increased to 30 minutes. After dewaxing, sintering was carried out with the sample placed on a support, which worked as the cathode of a 80% Ar + 20% H-2 discharge at a pressure of 1330 Pa (10 Torr) for 30 minutes. Characterization of the sintered samples showed that plasma technology resulted in an efficient process.
