Evaluation of Surface Changes under Twin Disc Tests

• In order to choose the right manufacturing process in terms of costs and component performance, three differently manufactured surfaces were investigated: brushed, multiple shot-peened and phosphated surfaces. In-house twin disc tribometer was used to test the wear and fatigue performance of the different surfaces. The evoution of the surface topography has been evaluated by in-line stylus and microscope image measurements as well as interference measurements of replicas taken at various test intervals. The form changes has been assessed by stylus measurements. The results have shown that the surface roughness played the major role to wear and fatigue performance.
