Quantitative Surface Topography Characterisation and the Hunt for Functional Relationships Seminar

Date: Thursday 19 September 2013 at 2:00pm
Location: Lecture Theatre B, School of Mechanical Engineering.
Taken by: Professor Richard Leach, Principal Research Scientist, Engineering Measurement Division, National Physical Laboratory.

Abstract: The measurement and characterisation of surface topography has come a long way since the days of single profile measurements with a stylus instrument. We can now measure three-dimensional, multi-scale surface topography using a range of instruments and follow this up with a multitude of mathematical characterisation techniques. Over the last decade, NPL has been developing the traceability infrastructure to support these measurements. ISO standards are beginning to be published, and physical and software measurement standards are now available. NPL is also investigating how tolerancing can be applied when designing surfaces with a given function in mind. Example include the use of laser dimpling to affect bearing surfaces or the structuring of a surface to affect bio-compatibility. The talk will discuss the latest advances at NPL.

This seminar has been organised by the Institute of Engineering Thermofluids, Surfaces and Interfaces (iETSI).
