WEAR UNDER LUBRICATED SLIDING CONTACTS - A DIMENSIONAL ANALYSIS MODEL
Keywords:
Wear, Dimensional Analysis, Deep drawing , AdditivesAbstract
The aim of this research was to investigate and analyze the wear of commonly used die material (AISI 4140) under lubricated sliding contact with low carbon steel sheet. Mineral based oil blended with sulfur and ester was used. A mathematical model considering lump parameters was developed using dimensional analysis technique. Tribo-experiments were conducted on a dedicated test set-up which simulates the actual contact conditions as in sheet metal drawing operation. This paper highlighted the wear characteristics of a lubricant containing specific additives under sliding contact conditions to anticipate the wear so as to render it a suitable lubricant for deep drawing operation.
