An Assessment of the Abrasive Wear Behavior of Ferrous Alloys and Composites Using Small Scale Laboratory Wear Tests
- NETL
Laboratory wear tests are only truly effective when they closely simulate the wear processes experience by the test piece in the field. Typically, laboratory wear tests only approximate the two- and three-body wear systems of the tribo-environment. The Albany Research Center uses a suite of three laboratory abrasion and impact-abrasion wear tests to rank materials for wear applications. 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); and (3) high-speed, impeller-tumbler (impact-abrasion). Subsequently, candidate materials can be ranked according to their performance for each of the wear tests. The abrasion and impact- abrasion test methods will be described, highlighting the predominant wear mechanisms for each test. Data on a wide variety of iron and steels will be presented, with relative ranking of the materials according to the specific wear test.
