Abstract
The surface defects of aluminum alloys that have undergone high temperature processing are studied. The effects of rolling passes and forward speed on the generation of a disturbed layer on aluminum alloy sheet surfaces were investigated with a hot rolling simulator. The results showed that by increasing the forward speed and number of rolling passes, the localized shear deformation became more pronounced on the surface. However, when the two rolling passes were in opposite directions, the defects induced by the localized shear deformation were embedded into the aluminum surface. The use of WS2 as a solid lubricant in hot forming of AA5083 aluminum alloy was also explored. The results show that the method of WS2 application is crucial to its performance. An aerosol WS2 spray was developed which recorded a lower COF than BN and a WS2 coating sandblasted to the substrate. WS2 also showed better durability regardless of application method than BN.
