Abstract

Recently several new technologies are introduced to achieve high density of PM such as warm compaction, surface densification, high velocity compaction and so on. Die wall lubrication is one of these technologies. However, the study of quantitative analysis of die wall abrication is very few, neither the suitable lubricant for die wall lubrication. The authors studied the die wall lubrication technologies itself comparing TRIBO type and CORONA spark type and also studied several lubricant electric charge value. Trough these studies, the new lubricant for die wall lubrication is synthesized.
