近年来，在涂层和其他材料的磨料磨损测量中，微观磨损试验已成为非常流行的方法。一个欧盟资助的项目刚刚完成，该项目旨在开发测试方法，并将现有的CEN ENV测试修订为完整的标准。该项目的关键方面涉及测量的准确性，通过实验室间练习测试方法的重复性和再现性，以及测量方法对不同类型涂层的工业适用性。可以应用的主要测量方法是光学测量和轮廓测量。在这里，人们发现，轮廓测量提供了重要的信息，在测试过程中产生的陨石坑的形状，但光学测量被认为是足够的，在大多数情况下。在比较不同实验室的结果时，发现光学测量的重现性约为2%。14个机构参加了实验室间的工作。这为测量方法找到了合理的再现性和重复性。本文最后描述了在项目结束时建议的程序，并有可能在CEN中采用。ASTM和ISO标准。(c)2005 Elsevier B.V.保留所有权利。
The mico-scale abrasion test has become very popular in recent years for the measurement of the abrasive wear of coatings and other materials. A EU-funded project has just been completed that had the aim of developing the test method, and revising the existing CEN ENV for the test into a full standard.Key aspects of the project were concerned with the accuracy of measurements, the repeatability and reproducibility of the test method through an interlaboratory exercise, and the industrial applicability of the measurement method to different types of coatings.The main measurement methods that can be applied are optical measurements and profilometry. Here, it was found that profilometry measurements gave important information on the shape of the crater produced during the test, but optical measurements were found to be adequate in most cases. The reproducibility of the optical measurements was found to be about 2% when the results of different laboratories were compared.Fourteen organisations participated in the interlaboratory exercise. This found reasonable reproducibility and repeatability for the measurement method. The paper concludes by describing the procedure that was recommended at the end of the project, and is likely to be adopted in CEN. ASTM and ISO standards. (c) 2005 Elsevier B.V. All rights reserved.
