Corrosion‐Protection of T122 Steel Using g‐C3N5‐Embedded Epoxy Coatings

Materials and Corrosion, EarlyView.
Study evaluates g‐C3N5 (CN) reinforced epoxy coatings on T122 steel in NaCl and H2SO4. Electrochemical tests revealed that 2% loading maximizes corrosion resistance by blocking pores and limiting ion diffusion, increasing Rp and Rn. Optimized CN content enhances epoxy coating performance overall system durability material. ABSTRACT Corrosion‐protection

Potentiodynamic Polarization Behaviour of Electroless Ni-P-W Coatings [PDF]

ISRN Corrosion, 2012
This paper deals with the synthesis of electroless Ni-P-W coatings on mild steel substrate followed by furnace-annealing process. Corrosion behaviors of the coatings after heat treatments at various annealing temperatures are evaluated by potentiodynamic polarization test using 3.5% sodium chloride solution.

Corrosion Inhibition of S275 Carbon Steel in CO2 Capture Systems Using Monoethanolamine (MEA) Solvent

Materials and Corrosion, EarlyView.
Corrosion inhibitors CuSO4 and NaVO3 achieved up to 98% inhibition efficiency for carbon steel S275 in CO2‐loaded MEA solvent, reducing corrosion rates to 9.4 µm/year—outperforming costly stainless steel SS 316 L at a fraction of the cost. ABSTRACT Corrosion in CO2 capture units significantly impacts safety and costs.

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

Materials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...
