Abstract
The acid‐resistant steel represented by 09CrCuSb (ND) steel that is widely used in flue gas treatment systems is easily prone to mixed‐acid dew point corrosion in the low‐temperature flue gas environment. To improve the corrosion resistance of ND steel in a low‐temperature dew point corrosion environment, here, a chromium–myristate hybrid (CMH) superhydrophobic coating is proposed as a low‐temperature dew point corrosion protective coating for the ND steel substrate. This superhydrophobic coating is deposited on the ND steel substrate (preplated dark nickel as a transition layer) by one‐step direct current electrodeposition. The electrochemical analysis from potentiodynamic polarization and electrochemical impedance spectroscopy and the immersion test show that the CMH superhydrophobic coating can significantly improve the corrosion resistance of the ND substrate. Therefore, the present study provides a feasible strategy for preventing the mixed‐acid dew point corrosion of ND steel in the low‐temperature zone.
