“…The liquid flow and the harsh soil environment erosion on the pipe wall cause economic losses, catastrophic accidents, and environmental pollution. [2][3][4] Over the last decades, investigations have been conducted extensively on the corrosion and wear resistance of pipeline transport steel, [5][6][7][8][9] indicating that coating is an efficient way to protect the pipeline from wear and corrosion. Organic coatings, including phenolic epoxy resin, powder epoxy resin, polyethylene, polyurethane, polyamide, 10,11 were widely used on pipeline protection combined with cathode protection.…”

Different mill additives were optimized to improve enamel coatings anti sulfuric corrosion, the immersive corrosion behaviors in 30 wt. % H2SO4 solution for 120 days of the above enamel coatings were investigated by XRD, SEM‐EDS, LSCM, Raman spectra, OCP, and EIS techniques. Results showed that the enamel coating with 12 wt. % quartz mill additives presents the best corrosion resistance. The mill additives significantly reduced the porosity, increased the silicon‐oxygen network density, enhanced the gel passivation layer formation ability of enamel coatings, increased the alkaline oxide content, and prevented the ion exchange within the sulfuric acid solution.This article is protected by copyright.
