Surface topography and integrity after finishing operations
Generating desired functional properties on surfaces remains a challenging scientific and industrial problem. For example, the metal surface appearance is affected by: topography, structure, and microlayers. In , surface topography was studied with regard to aesthetics and shininess. The gloss was with a glossmeter kindly donated by Zehntner GmbH Testing Instruments. Further studies on surface roughness parameters in 2D and 3D suggested a procedure to select parameters as performance index . In particular, scale-area analysis and functional roughness parameters need to be considered for a holistic and robust evaluation. In a collaboration with Prof. Jörg Seewig, MTS, University of Kaiserslautern, angle-resolved scattered light sensors were used to assess surface topography changes in vibration finishing processes .
