Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of the abrasion resistance of coatings by a micro-scale abrasion test (ISO 26424:2008) EN ISO 26424:2016

Publication date:   Aug 16, 2016

Scope

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.
