三维表面测量的发展

在过去八年里，三维表面测量已经由一个新鲜事物发展成为评估工程表面特性的重要依据，并得到广泛应用。表面形貌对于表面特性，如摩擦、磨损、腐蚀、疲劳、涂层等，具有举足轻重的影响。为了充分分析和研究表面特性，表面测量与评估应按三维考虑。近年来，许多世界上著名的学术团体已致力于研究一个系列的三维表面粗糙度标准。作者在本文介绍近年来三维表面评定和标准化的进展。

Advance in the Three-Dimensional Surface Metrology

Over the past eight years the subject of 3D surface metrology has developed from something of a novelty to a position where it has now become a crucial tool in the characterisation of engineering surfaces across a broad range of applications. It is widely accepted that the nature of the topography of a surface has a significant influence on the efficiency and functional performance of the surface include wear, friction, lubrication, corrosion, fatigue, coating, paintability, etc. It is also increasingly being recognised that in order to fully study and control surface manufacture to enhance the above applications, studies need to be carried out from a 3D perspective. A number of key research groups have been working in this area in an effort to produce definitive 3D surface roughness standards. This paper reviews the most recent work in the field of 3D surface characterisation and outlines the development towards a 3D surface roughness standard.
