As a typical two-dimensional (2D) MXene, Ti3C2O2 has been considered as potential material for high-performance hydrogen evolution reaction (HER) catalyst, due to its anticorrosion and hydrophilic surface. However, it is still challenge improve the surficial HER catalytic activity. In this work, we investigated activity of after surface was doped with S, Se, Te by first principles method. The r...

High-strength naval steel panels were coated by spraying with five commercial antifouling paints. The first set of specimens was subjected to electrochemical measurements and the anticorrosion properties paints evaluated under controlled laboratory conditions. A second series samples statically exposed for nine months in thirteen different harbors, located Mediterranean Sea Atlantic Ocean, wher...

Superhydrophobic epoxy nanocomposites coatings with superior mechanical and adhesion strength are targeted to increase coating performance protect steel corrosion in aggressive environment. The present work prepared hydrophobic organic modified inorganic nanoparticles (NPs) based on magnetite, titanium dioxide silver capped epoxide oleic, linoleic linolenic fatty acids. Their chemical structure...

The malt bagasse is a solid residue, highly produced in the brewing industry. presence of high levels antioxidants its composition makes this residue an attractive possibility as corrosion inhibitor, besides being sustainable and low cost alternative to inorganic procedures currently used prevent corrosion. In sense, work evaluated efficiency powder inhibitor on surface AISI 1020 carbon steel, ...

Amorphous silica thin films were applied on the 316L stainless steel substrates by sol-gel dipping technique. The starting chemicals (TEOS, ethanol, HCl, PEG, and NaOH) were used to prepare a gel and then deposited on a substrate. The microstructure, topography, corrosion behavior, and surface hardness were investigated using SEM, AFM, electrochemical method, and micro-hardness measurements. Th...

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...
