Fe-based amorphous alloys (FAA) have excellent anti-corrosion and anti-abrasive comprehensive performances. However, sprayed thin FAA coatings with high porosity cannot provide efficient protection, or even accelerate the corrosion rate of substrate due to galvanic corrosion. Laser re-melting densifying is usually used improve performance coatings. There are two disadvantages common laser metho...

The inherent reactivity of the Al–Cu alloys is such that their use for structural, marine, and aerospace components and structures would not be possible without prior application of a corrosion resistance system. Historically these corrosion resistance coatings were based on the use of chemicals containing Cr (VI) compounds. Silane coatings are of increasing interest in industry due to th...

The anticorrosion potency of Sabic mild steel (MS) in 0.5 M H2SO4 solution was enhanced by three synthetic non-ionic surfactants (NI Surf.) containing pyridine and pyrimidine derivatives. These compounds are safe, environmentally friendly, harmless to human health. Chemical electrochemical measurements were used compute the corrosion parameters. efficacy increases with increasing concentration ...

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.) ...

In this study, inspired by the adhesion protein of mussels, a Zn2+-loaded polydopamine (PDA/Zn2+) coating was prepared on an alkali–heat-treated magnesium alloy surface, through chelating effect PDA with metal ions, to improve anticorrosion and biocompatibility. The results water contact angles show that PDA/Zn2+ coatings different Zn2+ contents had excellent wettability, which contributed sele...

Bio-based epoxy resins are attracting widespread interest in the field of polymer thermosets as environmentally friendly building block. In present study, feasibility applying UV-curable epoxidized vegetable oils (EVOs) anti-corrosion coating is investigated. Rheological characterization EVOs carried out, and their viscosity-shear relationship evaluated. The cationic UV-curing successfully give...

Encapsulated anticorrosion agents provide a suitable alternative to dispersion of metal-based compounds in protective polymeric coatings on metal substrates. Stimuli-responsive microcapsules enhance protection abilities by autonomously responding corrosion-induced environmental changes, rather than relying damage-induced mechanical stimuli. This work reports pH-responsive with triggered release...

The easy and scalable synthesis, biocompatibility, one-dimensionality, high aspect ratio, viability for surface modifications, the ability cargo-loading release make organic nanotubes ideal candidates smart coatings with slow controlled corrosion inhibitors anti-biofouling agents. wide-ranging applicability of as nanocarriers anti-corrosion is foreseen.
