Experiments Bending under tension is a well-established friction test method[20]. The test was developed to simulate the contact between thedie and the workpiece surfaces and the deformation of a sheet metalat the die radius. In this investigation, the experimental set-up wasdeveloped using a draw bench. Prepaint specimen and lubricantused in the experiments were provided by a collaborator in indus-try. The performance of different coatings under different die radiiand lubrication conditions was investigated in order to correlatethe testing parameters to the surface quality after forming.
