Study on Electrochemical Corrosion Rate of Braided Wire Rope

Abstract

Taking 8×19 traction galvanized Braided steel wire rope as the research object, we carried out the electrochemical corrosion test of the steel wire rope matrix and the galvanized layer. And the response surface method was used to examine the influence of the interaction of three factors on the corrosion rate of steel wire rope. The results show that the corrosion rate of the braided steel wire rope matrix and the galvanized layer increases with the increase of temperature and the decrease of pH value, and increases first and then decreases with the increase of Cl− concentration. There is a nonlinear relationship between corrosion rate and temperature, Cl− concentration and pH value. In the same corrosive environment, the corrosion rate of the galvanized layer of the wire rope is greater than the corrosion rate of the matrix. The influence degree of the three factors on the corrosion rate of the steel wire rope matrix and the galvanized layer under the interaction is: pH>temperature>Cl− concentration.
