Figure 11

First and second line: SEM images and C, O, and Fe elemental concentration maps of a steel sample, measured by AES immediately after scratch under high vacuum conditions and after short venting at atmosphere (10 min). Last line: sputter depth profiles before scratch, after scratch under UHV, and after 10 min venting at environmental pressure.
