The development of anticorrosion coatings on copper has raised tremendous interest in material science. Using a milling method, regular rough structures were fabricated, and after chemical deposition with AgNO3 solution the modification stearic acid, superhydrophobic substrate could be obtained. surface morphological study showed dendritic microstructure, rectangular bulge produced by was distr...

In this study, the corrosion resistance of a bituminous coating reinforced with different ratios of nanoclay pigment was studied. To make nanocomposite coatings, 2, 3, and 4 wt.% of clay (Cloisite Na+) were incorporated into water emulsified bitumen. The coatings were applied to steel 37. Optical microscopy and X-ray diffraction (XRD) were used to characterize the nanocomposite structure. In or...

The synthesis of polyaniline- Fe2O3 nanocomposite coating on aluminum Alloy 5052 (AA5052) surface has been investigated by using the galvanostatic method. The anticorrosion performance of polyaniline-Fe2O3 coating was investigated in 3.5% NaCl solution by the open- circuit potential (OCP), Tafel polarization technique and Electrochemical Impedance Spectroscopy (EIS). The corrosion rate of polya...

Abstract According to the anticorrosion demand of petrochemical pressure vessel storing acid medium, phenolic epoxy resin and modified amine curing agent was used, a tertiary accelerator added, fast-curing acid-resistant anticorrosive coating with excellent acid-resistance developed by adding appropriate amount flake pigments fillers such as graphene chemical additives. Through Performance Test...

Abstract This work presents the experimental research carried out to optimize a current computational software “CorOns”, obtain better ship hull electrical signature modelling. Middle-term ageing (597 days) of anticorrosion paints, highlights appearance additional corrosion processes, despite an absence visual defects. A specific model is proposed for aged surface in seawater based on Electroch...

Initially, pristine polymers were used to develop corrosion-resistant coatings. Later, the trend shifted use of polymeric nanocomposites in anti-corrosion materials. In this regard, graphene has been identified as an important nanomaterial. Consequently, polymer/graphene have applied for erosion protection applications. Among polymers, conducting (polyaniline, polypyrrole, polythiophene, etc.) ...
