摘要：

The effect of tempering temperature (560 degrees C, 600 degrees C and 640 degrees C, denoted as T560, T600 and T640, respectively) on the corrosion behavior of R5 steel (a kind of mooring chain steel) in artificial seawater was studied by immersion tests and electrochemical measurements combined with scanning electron microscopy (SEM). X-ray diffraction (XRD) was conducted to analyze the corrosion products. The results indicated that the corrosion resistance of the steel was increased with elevating tempering temperature. Steel T640 with higher tempering temperature exhibited excellent corrosion resistance with lower corrosion current density, a less weight loss and bigger impedance modulus than steels T560 and T600. The distinction of corrosion resistance can be attributed to the different grain size and carbide density in the microstructure.
