GB/T 45593-2025 Fine ceramics—Determination of the abrasion resistance of coatings by micro-scale abrasion test

Scope

This document describes a micro-wear test method for determining the wear rate of fine ceramic coatings based on the ball pit method for measuring the thickness of ceramic coatings in ISO 26423 [2].
Note: This document obtains the wear rates of the coating and substrate through two independent ball pit tests or a single series of ball pit tests.
This document is suitable for testing samples with flat or non-flat surfaces. The results analysis described in this document (Chapter 9) is only applicable to flat samples; for non-flat samples, numerical methods are used for analysis [3], [4]. [1]: ISO 26423 is a standard for measuring the thickness of ceramic coatings, which can be translated as "ISO 26423". [2]: ISO 26423 is a standard for measuring the thickness of ceramic coatings, which can be translated as "ISO 26423". [3]: Numerical methods are used to analyze the wear rate of non-flat samples, which can be translated as "numerical methods". [4]: Numerical methods are used to analyze the wear rate of non-flat samples, which can be translated as "numerical methods".
