Electrochemical Corrosion Behavior of Carbon Fiber/Vinyl Ester Resin Composite Used for Sucker Rods

Abstract:

Article Preview

The electrochemical corrosion behavior of carbon fiber/vinyl ester resin composite (CF/VE), which has been used for sucker rods in the oil field, was studied under an immersion condition of 3% NaCl aqueous solution at 65°C. Galvanic corrosion experiment between the CF/VE composite and the alloy used as joints linking the composite sucker rods and metal suckers was performed. The results show that in a polarization system, there are a cathode reaction of oxygen absorption on the surface of the composite and an anode reaction, which is mainly depended on the concentration of the hydroxyl (OH¯). A slight acceleration of the absorption behavior and the decrease in the mechanical properties of the CF/VE composite are caused by the galvanic corrosion.
