Defines 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.

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 ISO26423 [11] . 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 Clause9 applies only to flat samples. For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
