摘要

Surface contacts represent a severe environment for even the most robust materials. High localized pressures and temperatures at asperity peaks can lead to a wide variety of wear regimes and chemical events that ultimately lead to the failure of a bearing surface.rnWear rates of sliding surfaces can be measured in a variety of ways. Mass measurements can be taken before and after tests to provide an average wear rate, provided that the materials of interest do not uptake or outgas mass in the test environment. A wide range of commercially available profilometers, interferometers, and optical/electron microscopes can be used to geometrically characterize material loss once a test is complete.rnIt is often desirable to perform real-time wear measurements and observe initial run-in (or transient) periods, sudden material failures, and other wear events. One approach is to monitor the relative normal displacement between two surfaces, then calculate a wear rate from knowledge of the contact geometry. This can be troublesome if both components of the contact are simultaneously wearing. Chemical events can also be monitored in real time through the use of in-situ spectroscopy.
