Tribološki aspekti korišćenja Al-legura pri dubokom izvlačenju tankih limova

Abstract

During the last few years the consumption of new materials in fabricatin of passenger cars has grown. The application of Al-alloys sheet matal, first of all in the manufacture of carbody elements, is extremely important. Formability of Al-alloys is reduced in comparison to steel sheet matals. That is why the tribological conditions and formability parameters are extremely important in deep drawing process. This papers presents the results of research in the area of mechanism of friction in the contact zones between steel/Al-alloy (sliding test) and description effect of tribilogical conditions (surface topography, tool surface and lubricant) in deep drawing.
