Introduction
This document provides new and improved methods for testing the abrasion characteristics of
hardmetals using rotating-wheel systems. There are a number of abrasion test methods that have
been developed that use this type of geometry, including the ASTM G65 dry sand/rubber wheel test,
the ASTM G105 wet sand/rubber wheel test and the ASTM B611 steel wheel test. Other variants of
these tests have also been developed for specific applications in other institutes. All of these tests use a
rotating wheel pressed against a test piece, with abrasive material introduced between the wheel and
the test piece. Because of this fundamental commonality, much of the methodology is the same for the
different tests. However, they do differ in the details of how the abrasive is fed to the interface between
the wheel and the test piece, if the test can be carried out in the presence of fluids, and if the abrasive is
only used once and passes through the test system, or is reused many times.
This document provides framework that brings together the key features of these tests and gives
results that show comparability. It also gives information on their reproducibility and repeatability.
The procedure complements the ASTM G65 method for dry sand/rubber wheel abrasion,
the ASTM B611 method for determining the high stress abrasion of hard materials, and the
ASTM G105 method for conducting wet sand/rubber wheel abrasion tests.
Abrasion wear is not a measure of the wear characteristics of hardmetals under all conditions, and
should not be misinterpreted as indicating wear when hardmetals are used for tooling, such as cutting
and milling. It does show the difference in resistance to abrasive use for different carbide compositions,
and the methods may be used as practical tests or as research methods for material discrimination.

3.3
abrasion wear
wear caused by a slurried abrasive on a rotating surface contacting the test-piece surface under

4 Principle
The test uses a rotating wheel against which test pieces are pressed. Abrasive is introduced between
the wheel and the test piece to cause abrasion to the test piece.
5 Materials
5.1 Test pieces
5.1.1 Overall sizes
Test pieces are typically larger than the contact area with the rotating wheel and are typically 40 mm
to 70 mm × 20 mm to 25 mm in size. These test pieces are designed to allow for the wear scar to be
[1]
contained wholly within the area of the contact face. However, some variants of the test (see in the
Bibliography) use a test piece with a clearly defined contact shape and size where the wear takes place
across the entire contact face of the sample. The thickness of the test piece is not important, as long as it
is sufficiently robust and the wear takes place entirely within the test piece.
When coated samples are tested, the test duration is normally adjusted to ensure that the wear occurs
exclusively within the coating. This can be determined by post-test examination.
5.1.2 Surface finish
The surface finish of the test piece may affect the results of the test. Thus, the presence of a surface that
is weakened by the preparation process may lead to increased initial wear. Conversely, the presence of
a residual compressive stress in the surface layer may possibly reduce initial wear
