Fine ceramic micro-wear test to determine the wear resistance of coatings
ScopeThis document describes the microwear method for determining the wear rate of fine ceramic coatings based on the ball crater method for determining the thickness of ceramic coatings in ISO 26423 [2].
Test method.
Note. This document obtains the wear rate of the coating and substrate through two independent ball pit tests or a single ball pit series test.
This document is applicable to the testing of specimens with planar or non-planar surfaces. The result analysis described in this document (Chapter 9) is only applicable to planar tests.
For non-planar samples, numerical methods are used for analysis [3], [4].

Terms and DefinitionsThe following terms and definitions apply to this document.
3.1
Abrasive wear rate
Material wear volume per unit sliding distance under a normal contact load of 1N.
Note. The unit is cubic meter per Newton meter [m3/(N·m)].
4 Principle
During the test, the grinding slurry is dripped into the contact area between the ball and the sample, and the ball is pressed on the sample and rotated, and a spherical concave
When the coating is not worn through, the wear rate of the coating is obtained from a single ball pit; when the coating is worn through, the wear rate of the coating is obtained by measuring the size of the pit.
The size of these craters is measured and the wear rates of the coating and substrate are calculated.
5.Instruments and Materials
5.1 Test system
Using a test ball that can rotate and press on the surface of the coating sample, there are two types of test ball systems. one is a free ball system,
The deadweight of the test ball presses against the test specimen [see Figure 1a)]. Under normal circumstances, the inclination angle is 60°~75° and the shaft groove width is 10mm; the other is
