Boosting Erosion‐Corrosion Resistance: Collaborative Ni–P Electroless Deposition on Poly‐Amino‐Alcohol@Functionalized GO Matrices

Abstract In recent years, protective coatings have become crucial in graphene‐based chemical studies. This research investigates the anticorrosive properties of coatings created by co‐depositing carbon compounds. Electroless Ni−P‐PAA@F‐GO coatings were applied to stainless steel by adding various amounts of PAA@F‐GO particles to the Ni−P bath. The coated samples were analyzed using X‐ray diffraction and micro‐hardness tests, revealing a peak hardness of 764 HV at 30 mg/L PAA@F‐GO, compared to 521 HV for standard Ni−P coatings. Corrosion performance was evaluated in a 3 % sodium chloride solution, showing that despite a higher corrosion‐erosion rate. Although the coated samples exhibited a corrosion‐erosion rate 4.7 times higher than untreated samples, the mass loss was notably more pronounced in the untreated samples. The study found that adding PAA@F‐GO particles improved corrosion resistance and durability, with optimal results at a specific particle concentration. The enhanced performance is attributed to the increased roughness, impermeability, and hydrophobicity of the functionalized graphene oxide.
