Corrosion Behavior of X80 Steel Treated with Nickel Based Alloy Electroplating Coating in Fushun Soil Simulated Solution
Electroless plating is an effective technique for improving the corrosion resistance of materials. In this article, the electroless plating method was used to deposit Ni-Fe-P coating on X80 steel. The surface morphology of the coating was observed using scanning electron microscopy, and the structure of the coating was analyzed using X-ray diffraction technology. The corrosion behavior of X80 steel and the coating in Fushun soil simulated solution was tested using an electrochemical workstation. The results showed that there were typical cellular structures on the surface of the Ni-Fe-P coating, and the coating had good compactness. The phosphorus mass fraction in the coating was about 9.8％, and the coating had amorphous structure. The polarization curves and electrochemical impedance curves both indicated that the coating improved the corrosion resistance of X80 steel in Fushun soil simulation solution. This was mainly because the amorphous structure of the coating reduced the number of coating defects, reducing the number of corrosive micro batteries, and improving the corrosion resistance of X80 steel.
