Evaluation of Surface Preparation Techniques for Steel Substrates Prior to Coating Application
The performance of organic coatings on steel substrates is strongly affected by substrate cleanliness and anchor patterns. During present research work, Surface pre-treatments were applied to remove contaminants from steel surfaces. Electrochemical Impedance Spectroscopy (EIS) was used to characterize such surfaces in terms of electrochemical parameters to find out the extent of activeness of prepared surfaces, and electrochemical processes are modeled into corresponding electrical equivalent circuits (EECs). Surface roughness parameters were evaluated to find out the extent of mechanical interlocking between prepared surface and the coating to be applied over it. The optimum surface preparation technique prior to application of organic coating was characterized.
