Figure 7From: Surface analytical approaches contributing to quality assurance during manufacture of functional interfaces Results of non-destructive surface analysis using Optically Stimulated Electron Emission (OSEE) for freshly ground SAE 1008/1010 and 1.4301 steel during exposure in dry air. The horizontal dashed lines at the left side of the plot indicate the OSEE signals of as-received steel samples. Horizontal dashed lines at the right side indicate OSEE signals remaining basically unchanged after approximately two hours of exposure in air.Back to article page
