Specimen Carburization by Electron-Beam Contamination


Carburization of iron specimens by contamination from the electron microscope had previously been observed. In more recent experiments, carburization did not occur. The difference in behavior was traced to a difference in the pump oil used. These results support the view that the diffusion pump oil is an important source of contamination in the electron microscope.
