Dry Abrasion Tester
The Dry Abrasion
Tester is used to test the abrasive resistance of solid materials to abrasive
dry sand compositions. Materials such as metals, minerals, polymers,
composites, ceramics, abrasives, and thick coatings can be tested with this
instrument. The test is performed by loading a rectangular test sample
against a rotating rubber wheel and depositing sand of controlled grit size,
composition, and flow rate between them.
The wheel, comprised of synthetic rubber of 60 Shore A hardness, is rotated
in the direction of the flow of sand. The mass of the test sample is recorded
before and after conducting a test and the difference between the two values
is the resultant mass loss due to dry sand abrasion. To develop a comparison
table for ranking different materials with respect to each other, it is
necessary to convert this mass loss to volume loss to account for the
differences in material densities.
The test load and sand composition can be varied. The test parameters can be
configured to perform tests as per ASTM G65 specifications.
