Overview

This International Standard 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. The text of ISO 26424:2008 has been prepared by Technical Committee ISO/TC 206 "Fine ceramics" of the International Organization for Standardization (ISO) and adopted as EN ISO 26424:2016 by CEN/TC 184 "Advanced technical ceramics", the secretariat of which is held by DIN (Germany). At present a DIN committee does not exist for DIN EN ISO 26424 since the parties concerned have not shown any interest in work on the subject.
