Fine ceramics (advanced ceramics, advanced technical ceramics). Determination of the abrasion resistance of coatings by a micro-scale abrasion test
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 ISOΒ 26423 [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 ClauseΒ 9 applies only to flat samples.
For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
