Abstract

A new rolling-type tribometer has been devised to investigate the effects on friction behavior of the average velocity of the lubricant at the inlet to the contact zone and the relative sliding velocity during deformation independently. This paper shows the principle of the tribometer and deformation mode of the workpiece, especially considering the relationship between friction and bulk deformation. Experiments using mild steel strips with a dull surface showed that the friction stress on the friction roll, which has a smaller velocity than that of the traction roll, is mainly controlled by lubricating conditions on the friction roll side. The contact pressure is mainly decided by the friction conditions on the traction roll side. It was also revealed that, with an increase of the reduction in the workpiece thickness, the friction stress on the friction roll side remains constant when the friction roll is rotated. The friction stress increases when the friction roll is stopped after a certain reduction in the workpiece thickness.
