Surface Texture Optimisation of Steel Sheets Considering Friction and PaintAppearance

摘要

In order to investigate the frictional behavior and the change in surfaceroughness of different sheet topographies, a bending under friction test, BUT, was used. This test exposes the material to bulk-plastic deformation under conditions similar to those present in the drawing radius of a real tool. Two significantly different sheet surface textures were investigated, electric discharge textured (EDT) and electron beam textured (EBT), with respect to frictional behavior. Each steel sheet material has been tested under different lubrication conditions. To measure the sheet surface topography a 3D stylus technique was used.
