Effects of inclusion on corrosion resistance of weathering

Nov 07, 2016· Wet/dry cyclic immersion corrosion test field emission scanning electron microscopy (FE SEM) metallographic optical microscope.,The indoor accelerated corrosion kinetics of Q450NQR1 weathering steel could be divided into two stages with different log (thickness loss, D) log (time, t) fitting functions, and the effect of inclusions on the corrosion resistance of Q450NQR1 weathering steel was Effect of micro phase electrochemical activity on the Therefore, Q355NHD and Q450NQR1 steels undergo micro galvanic corrosion at the initial stage of corrosion, resulting in a greater corrosion rate . Moreover, since the content of pearlite in Q355NHD is 10% higher than that of Q450NQR1 ( Table 2 ), the micro galvanic corrosion effect is Effects of inclusion on corrosion resistance of weathering Nov 07, 2016· Findings. The indoor accelerated corrosion kinetics of Q450NQR1 weathering steel could be divided into two stages with different log (thickness loss, D) log (time, t) fitting functions, and the effect of inclusions on the corrosion resistance of Q450NQR1 weathering steel was only reflected in the initial stages of corrosion.
