This application note explores the use of 3D parameters to characterize surface topography, as well as how 3D measurement can now provide a more complete picture of a surface's real variations and functional nature than was previously possible using Ra alone. Bruker experts explain the value and uses of different R and S parameters, then present two exclusive, real-world case studies in which these parameters were used for the design and development of high-performance surfaces.
It includes figures and tables clarifying and comparing the value and potential uses of different R and S parameters, two case studies showing the advantages of using S parameters for surface evaluation and design, and a collection of relevant standards with definitions and guidelines for surface parameters.
Download white paper here and learn why Ra has persisted despite its shortcomings and how S parameters can describe surfaces more completely.
