Wear and Erosion Test Equipment

In the 1960s the American Society for Lubrication Engineers (ASLE) listed more than 200 types of wear tests and equipment in use (Ref 1), and the list has since grown. This wide variety is the result of a desire to ensure appropriate controls, make tests convenient, and simulate the wear conditions of the intended application.

The equipment described in Ref 2 includes apparatuses specifically designed for laboratory use. Although many of these test configurations are one-of-a-kind machines, others are available as commercial units.

Standards related to wear and erosion testing are listed in Ref 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15. These standards do not suggest adequate test methods for wear or erosion resistance, but they relate to the testing of metals, plastics, refractory materials, and organic coatings. Reference 12 describes an abrasion tester that is essentially an airblast erosion rig. Reference 13 describes an erosion tester that is similar but different in detail. References 14 and 15 describe air-blast erosion test rigs for coatings.

References 16, 17, 18, 19, 20, 21, 22, and 23 give design details of the three most commonly used erosion test rigs: airblast rigs (Ref 16, 17, 18, 19 ), whirling arm rigs (Ref 20, 21, 22), and wind tunnel rigs (Ref 23). Reference 24 contains a general discussion of these erosion test methods.
