Aluminum-Silicon alloys are of considerable and growing interest owing to their use in automobile engines and other wear-intensive applications. Studies have indicated that the environment and the microstructure of alloys each play a significant role in wear behavior [1] [2] [3] . In this work, the wear of Al-Si alloys was studied in pin-on-disk tribotests in different environments, including air and dry argon. The counterface in all tests was yttria-stabilized zirconia. Both the worn Al-Si

The TEM specimens had been cut from the surfaces with the aid of a focused ion beam (FIB) microscope. Thinned samples were examined in a TEM operating at 200kV to which an energy dispersive x-ray spectrometer (EDS) was interfaced so as to collect elemental X-ray maps.
