Abstract
Characterisation of surfaces is of fundamental importance to control the manufacturing process and the functional performance of the part. Many applications concern contact and tribology problems, which include friction, wear and lubrication. This paper presents the techniques and instruments for characterisation of surfaces, discussing their operating principles and metrological properties. A review of the conventional 2D and new 3D roughness parameters is given, considering both the current standards and new proposals for texture quantification, with a particular attention to the methods orientated towards a functional characterisation of surfaces.
