SLURRY ABRASION TEST RIG AS PER ASTM G 105 & B 611

The Slurry Abrasion Test Rig as per ASTM G 105 & B 611 has been designed to determine the resistance of metallic materials to scratching the abrasion wet sand & rubber wheel. This test rig designed such that a standard specimen pressed against to rubber wheel with a known force. The test area is submerged wet abrasive slurry. The arrangement is such that the wheel carries grip particles across the contact face in the direction of wheel rotation.

Three wheels are required with nominal shore a durometer hardnesses of 50, 60 and 70, with a hardness tolerance of +/- 2.0. A run-in is conducted with the 50 Durometer wheel, followed by the test with 50, 60 and 70 Durometer wheels in order of increasing hardness. Specimens are weighted before and after each run and the loss in mass recorded. The logarithms of mass loss are plotted as a function of measured rubber wheel hardness and a test value is determined from a least square line as the mass loss at 60.0 Durometer. It is necessary to convert the mass loss to volume loss, due to wide differences in density of materials, in order to obtain a ranking of materials. Abrasion is then reported as volume loss in cubic millimeters.

The same test rig also covers the determination of abrasive wear resistance of cemented carbides.
