Specifičnosti triboloških karakteristika limova od Al-legura

Abstract

During the last few years the Al-alloys have found the exceptional application in car industry, for all key elements of the vehicle: car-body, drive group, wheels, interior etc. the formability of AL-alloy sheet metals intended for manufacture of car-body elements is significantly reduced in comparison to steel. That is why the tribological conditions are extremely important in the deep drawing process. The paper gives results for Al-Mg alloy sheet metals obtained by main tribo-investigations (sliding tests) in various pressure-speed conditions and with use of various lubricants.
