AbstractThe achievement of high density at reasonable cost would be a definite advantage for the production of P/M components requiring high static and dynamic properties. The use of the electrostatic die wall lubrication technique appears as a very attractive route to promote desification. by reducing the level of friction at die walls, this techniques should have the potential to also reduce density variations in powder compacts, particularly for parts having a large sliding surface or a long die fill. This paper presents two case studies of parts having high aspect ratio compacted using die wall lubrication either on a laboratory press or on an industrial mechanical press. Special attention is paid to the axial density distribution of the green compacts as a function of the compacting pressure and the type of lubrication (admixed or die wall lubrication).
