精细陶瓷(高级陶瓷、高级工业陶瓷).使用微尺度磨损试验测定覆层的耐磨性

[中文适用范围]： 本国际标准规定了一种通过基于 ISO 26423 [11] 中用于涂层厚度测定的已知凹坑研磨技术的微尺度磨耗磨损试验，来测量陶瓷涂层磨耗磨损率的方法。该方法可提供涂层和基体的磨损率数据，可通过进行两次单独试验或通过仔细分析单次试验系列的数据获得。该方法可应用于具有平面或非平面表面的样品，但第 9 章中描述的结果分析仅适用于平面样品。对于非平面样品，需要更复杂的分析，可能需要使用数值方法。 [外文原描述]： ISO 26424:2008 specifies a method for measuring the abrasive wear rate of ceramic coatings by means of a micro-scale abrasion wear test based on the well-known crater-grinding technique used for coating thickness determination in ISO 26423. The method can provide data on both coating and substrate wear rates, either by performing two separate tests or by careful analysis of the data from a single test series. The method can be applied to samples with planar or non-planar surfaces, but the results analysis described in the text applies only to flat samples. For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
