Tantalum, as a potential metallic implant biomaterial, is attracting more and more attention because of its excellent anticorrosion and biocompatibility. However, its significantly high elastic modulus and large mechanical incompatibility with bone tissue make it unsuitable for load-bearing implants. In this study, porous tantalum coatings were first successfully fabricated on titanium substrat...

The preparation of polyaniline/zeolite nanocomposite coating on 304 stainless steel (304 SS) surface has studied via the galvanostatic method. The electro-generated coating was characterized by Fourier transform infrared spectroscopy (FT-IR), UV-visible absorption spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The anticorrosion property of polyaniline/zeo...

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 The protective bronze film was prepared by mixing the reaction product of oligosaccharide (COS) and modified tannic acid (TA) with polyvinyl alcohol polyethylene glycol. Chloroacetic to carboxylate TA used generate sodium tannate. N,N’-Dicyclohexylcarbodiumide (DCC)/1-Hydroxybenzotriazole (HOBt) as a condensing agent form an amide bond between carboxylic amine COS-TA. synthesized chara...

Biocorrosion has been considered as big trouble in many industries and marine environments due to causing of great economic loss. The main disadvantages of present approaches to prevent corrosion include being limited by environmental factors, being expensive, inapplicable to field, and sometimes inefficient. Studies show that polymer coatings with anticorrosion and antimicrobial properties hav...

Carbon nanotubes (CNT) were dispersed into homemade silicone–polyurethane (SPU) resin in order to enhance their mechanical and anticorrosion ability. Before mixing with SPU, CNT modified by four different approaches improve dispersion the surface of covered SiO2–TiO2 nanoparticles, -NH2 groups, epoxy groups or isocyanate respectively. The structures CNTs checked XRD, FTIR, SEM. After being SPU ...

Abstract In this study, the possibility of obtaining a corrosion indicator from time series electrochemical impedance spectra acquired during immersion intact organic coatings was inspected. To generate wide distribution in performance, with different pigment volume concentrations were applied on AA2024‐T3 and cold‐rolled mild steel tested four electrolytes for exposure times. The relative rank...

Abstract The incorporation of inorganic nanofillers into polymeric matrices represents an effective strategy for the development smart coatings corrosion protection metallic substrates. In this work, wet-jet milling exfoliation was used to massively produce few-layer hexagonal boron nitride ( h -BN) flakes as a corrosion-protection pigment in polyisobutylene (PIB)-based composite marine applica...

Basalt rockwool wastes with large output, which are toxic and require expensive environmental treatment, produced during the production of rock wool. Hence, it is urgent to find an effective method reuse these materials. In this study, polyaniline (PANI)-coated basalt (BRWs) were prepared as fillers serve in coatings for anticorrosion study. Results show that PANI-coated BRW (PANI@BRW) had enha...
