Tribological Properties of Steel and Al-Alloys Sheet Metals Intended for Deep Drawing
Journal Title: Tribology in Industry - Year 2009, Vol 31, Issue 3
Abstract
During the last few years, aluminium alloys are increasingly more used in production of light constructions, especially for manufacture of light car bodies of passenger cars. From the aspect of tribological factors influence, experience in application of low-carbon steel sheet metals in manufacture of car body parts by deep drawing procedures up to now differs significantly regarding the application of Al-alloys. The paper presents the experimental results of tribological investigations of specified materials properties at sliding tests, as well as results at deep drawing with variable blank holding force. The combination of unfavourable formability parameters and sensitivity to tribological conditions at application of Al-alloys requires a particular approach to tools and technology designing in comparison with classic forming procedure.
