Abstract
When screening materials, laboratory abrasive wear testing is a quick and inexpensive way of obtaining large quantities on information on wear rates and wear mechanisms. Typical laboratory abrasive wear tests approximate two- and three-body abrasion. The Albany Research Center, however, uses a suite of four laboratory abrasion, gouging–abrasion, and impact–gouging abrasion wear tests to rank materials for wear applications in the mining and minerals processing industries. These tests, and the wear mechanisms they approximate, are: (1) dry-sand, rubber-wheel (three-body, low-stress abrasion); (2) pin-on-drum (two-body, high-stress abrasion); (3) jaw crusher (high-stress gouging-abrasion); and (4) high-speed, impeller–tumbler (impact–abrasion). Subsequently, candidate materials can be ranked according to their performance for each of the wear tests. The abrasion, gouging–abrasion, and impact–abrasion test methods are described, highlighting the predominant wear mechanisms for each test. Data on a wide variety of irons and steels are presented with relative ranking of the materials according to the specific wear test.
