What is ISO 26424 – Abrasion resistance of fine ceramic coatings about ?
ISO 26424 is one of the hosts of international standards that focus on fine ceramics.
ISO 26424 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 be applied to samples with planar or non-planar surfaces, but the analysis of the results described in Clause 9 applies only to flat samples. For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
Who is ISO 26424 – Abrasion resistance of fine ceramic coatings for ?
ISO 26424 on determining the abrasion resistance of fine ceramic coatings using the micro-scale abrasion test is useful for:
- Manufacturers of fine ceramic products
- Designers of fine ceramic products
- Quality control personnel
Why should you use ISO 26424 – Abrasion resistance of fine ceramic coatings ?
Although few protective coatings are subject to single wear processes, the abrasive wear resistance of such coatings can play a decisive role in their performance. Hence, knowledge of the abrasive wear resistance of ceramic coatings can help in the proper selection of coatings for applications where abrasion plays a major role in their degradation.
The micro-scale abrasion test described in ISO 26424 measures the abrasion resistance of both thin and thick coatings and of bulk materials. 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. Although the test is designed to allow quantitative measurement of abrasive wear coefficients, it can be adapted as a quality control test for use on real components.
In conclusion, the test method specified in ISO 26424 enables you to identify the abrasion resistance of fine ceramic components and thereby help you in monitoring their quality.
