Scanning Electron Microscope with
Energy Dispersive X-Ray Detector
for Element Analysis
X-ray Detector
Figure 1: Use of Scanning Electron Microscope​ to study surface detail at high magnification​
Figure 2: Deterioration of stainless steel support rail ​on paving on the outside of swimming pool
Figure 3: Detail of oxidation and pitting corrosion of the stainless steel ​surface
X 100
Figure 4: The corroded surface at a magnification of X 3,000 under the scanning electron microscope show the formation of crystals due to the evaporation of the swimming pool water containing chlorine.
Figure 5: The X-ray analysis from the detector shows that the crystals seen in Figure 4 are sodium chloride. The reddish-brown corrosion product has iron, chromium, and oxygen from the corroded stainless steel. No molybdenum is detected.​ Stainless steels without molybdenum are particularly susceptible to pitting corrosion in the presence of chlorides.
