| Abstract Scope |
Understanding the fundamental micro-mechanisms governing wear is crucial for developing novel materials with improved tribological behavior. It is understood that atmospheric pressure plays a key role in determining wear mechanisms, but characterizing these effects in sufficient detail presents an ongoing scientific challenge. The present study addresses this by using a scanning electron microscope (SEM) to simultaneously control air pressure, conduct wear tests, and characterize the results at high magnification. Here, the effects of atmospheric pressure on the wear mechanisms of 6061 aluminum alloy (as well as others) are systematically investigated using in-situ SEM microscale scratch testing and further characterized morphologically and chemically. The insights gained in this study provide guidelines for future material design and processing efforts for both space-based and atmospheric applications. |
