Corrosion mechanisms, processes - The Fabricator

Applying a corrosion prevention product to steel isnt enough. If the workpiece is contaminated with something as minor as fingerprints or steel fines, corrosion can get a foothold. Understanding the components that make up a corrosion cell, and how a corrosion cell works, is necessary in learning how to prevent corrosion from getting a start. Detecting steel tube and pipe corrosion using SEM analysisSubstrates with poor conductivity may disturb the electron beam, which can be overcome by using a thin gold film plating. This usually isnt a problem in the tube and pipe industry because most corrosion appears on conductive substrates. To a trained eye, corrosion on a steel sample is easy to recognize (see Figure 1, Figure 2, and Figure 3).
