Paper Title:
Effect of YbCl3-Zn-Epoxy Coating on MIC Behavior of Low Alloy Steel
  Abstract

In the present study, the rare earths element YbCl3 was added into the Zn-epoxy coating, and the MIC behavior of the low alloy steel specimen with YbCl3-Zn-epoxy coating in the sulfate-reducing bacteria (SRB) solution was investigated and compared with the specimen of Zn-epoxy coating. Experimental results show that both the YbCl3-Zn-epoxy and Zn-epoxy coating may offer effective protection for the basic low alloy steel. However, the corrosion potential of the specimen with YbCl3-Zn epoxy coating was obviously higher than the Zn-epoxy coating, suggesting that the YbCl3-Zn-epoxy coating may offer more favorable protection. Results of X-rays diffraction (XRD) and surface micrographs of specimens show that more sulfides and corrosion products of YbCl3-Zn-epoxy coating were produced which increased the shielding property of the coating. The mechanism about the effect of YbCl3-Zn-epoxy coating on MIC behavior was further discussed.
