“…There have been some papers in the last few years describing corrosion parameters of different coatings deposited or layers created on titanium [ 1 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] and its alloys: Ti6Al4V [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ], Ti13Nb13Zr [ 14 , 24 , 25 , 26 , 27 ]. The coatings were designed and produced particularly to enhance corrosion resistance [ 1 , 4 , 6 , 7 , 8 , 9 , 11 , 16 , 17 , 18 , 19 , 21 , 22 , 23 , 24 ] or the corrosion characteristics were determined only to verify whether and to what extent the applied coating may affect the degradation process [ 5 , 10 , 12 , 13 , 14 , 15 , 20 , 25 ]. The main difference between coated materials was the presence or the absence of an artificial titanium oxide layer created by oxidation in different conditions [ …”

“…The main difference between coated materials was the presence or the absence of an artificial titanium oxide layer created by oxidation in different conditions [ 1 , 3 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 15 , 19 , 20 ] such as direct voltage anodic oxidation, micro-arc oxidation (MAO), or hydrothermal oxidation. The coatings other than rutile/anatase were composed of some metals [ 12 ], polymers [ 4 , 5 , 11 , 13 , 14 , 15 , 16 ], organic compounds [ 25 ], ceramics [ 5 , 9 , 10 , 23 , 24 , 25 , 26 , 27 ], oxides [ 5 , 6 , 8 , 9 , 12 , 19 , 22 , 24 , 25 ], graphene and carbides [ 1 , 18 , 20 ], and bioglass [ 17 ]. It is to underline that the most effective way to increase the corrosion resistance of titanium surfaces is to create a smooth and nonpermeable oxide layer.…”

Titanium and its alloys are often used for long-term implants after their surface treatment. Such surface modification is usually performed to improve biological properties but seldom to increase corrosion resistance. This paper presents research results performed on such metallic materials modified by a variety of techniques: direct voltage anodic oxidation in the presence of fluorides, micro-arc oxidation (MAO), pulse laser treatment, deposition of chitosan, biodegradable Eudragit 100 and poly(4-vinylpyridine (P4VP), carbon nanotubes, nanoparticles of TiO2, and chitosan with Pt (nano Pt) and polymeric dispersant. The open circuit potential, corrosion current density, and potential values were determined by potentiodynamic technique, and microstructures of the surface layers and coatings were characterized by scanning electron microscopy. The results show that despite the applied modifications, the corrosion current density still appears in the region of very low values of some nA/cm2. However, almost all surface modifications, designed principally for the improvement of biological properties, negatively influence corrosion resistance. The reasons for observed effects can vary, such as imperfections and permeability of some coatings or accelerated degradation of biodegradable deposits in simulated body fluids during electrochemical testing. Despite that, all coatings can be accepted for biological applications, and such corrosion testing results are presumed not to be of major importance for their applications in medicine.

“…The protective mechanisms of conductive polymers have been explained using numerous hypotheses, such as that conductive polymers cause an electric field on the material substrate, preventing the passage of electrons from the metal to the oxidizing medium; that conductive polymers engender a dense and short porosity layer on the specimen substrate, constituting a barrier between the metal and the aggressive medium; and that they make formatting a protective metal oxide film onto the surface of the sample possible. Many research studies have established that conductive polymers in various situations can recover their original mechanical and electrical characteristics without important degradation [28][29][30][31][32][33][34]. Conducting polymers are effective for fast doping and de-doping with high charge densities; consequently, they are materials with special properties for use in various electrochemical processes.…”

In this work, electrochemical deposition techniques (galvanostatic and potentiostatic) were used to obtain coatings of a new composite polymer, 3-methylpyrrole—sodium dodecyl sulfate/poly 2-methythiophene (P3MPY-SDS/P2MT), on cobalt-based alloy samples for anti-corrosion safety. The use of sodium dodecyl sulfate as a dopant ion in electrosynthesis can have a relevant effect on the anticorrosive property of the composite polymer layer by blocking the entry of corrosive ions. The cobalt alloy specimen had an important impact on the electrochemical performance of the composite coating and this together with the presence of the polymeric layer was achieved by simultaneously constitution of a complex oxides film and polymeric layers. The polymeric coatings were analyzed using scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and cyclic voltammetry (CV) methods. The corrosion protection of the P3MPY-SDS/P2MT-covered cobalt-based alloy was explored using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization procedures in a 1 M HCl solution. The corrosion speed of the P3MPY-SDS/P2MT-covered cobalt-based alloy was observed to be ~10 times less than an uncovered specimen, and the effectiveness of the composite layers of this coating is greater than 91%. This superior efficaciousness was obtained by the electropolymerization of P3MPY-SDS/P2MT at current densities of 1 mA/cm2 and 0.5 mA/cm2, applied potentials of 0.9 V and 1.0 V, and a molar ratio of 5:1. Corrosion test results indicate that the P3MPY-SDS/P2MT coatings provide a good result: protection against the corrosion of a cobalt-based alloy in aggressive solutions.

“…Notably, hydrophobic octadecylphosphonic acid (ODPA) coatings were prepared on oxidized copper mesh for self-cleaning and oil/water separation and on titanium dioxide for anti-fouling biomedical applications [40,41]. In addition, ODPA coating has been used to modify the surface of Ti6Al4V alloys to improve the corrosion resistance [42]. The hydroxyl groups on the surface of TiO 2 and Cu(OH) 2 facilitate the coating of ODPA on the metal surface [40,41].…”

To design more environmentally friendly, economical, and efficient demulsifiers for oily wastewater treatment, hydrophobic octadecylphosphonic acid (ODPA)-modified Fe3O4 nanoparticles (referred to as Fe3O4@ODPA) were prepared by condensation of hydroxyl groups between ODPA and Fe3O4 nanoparticles using the co-precipitation method. The prepared magnetite nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric/differential thermogravimetric (TG/DTG) analysis. The water contact angles (θW) of Fe3O4@ODPA nanoparticles were more than 120°, indicating hydrophobic nature, and the diameter of the obtained spherical-shaped magnetite nanoparticles was 12–15 nm. The ODPA coating amount (AO) (coating weight per gram Fe3O4) and specific surface area (SO) of Fe3O4@ODPA were 0.124–0.144 g·g−1 and 78.65–91.01 m2·g−1, respectively. To evaluate the demulsification ability, stability, and reusability, the magnetite nanoparticles were used to demulsify an n-hexane-in-water nanoemulsion. The effects of the magnetite nanoparticle dosage (CS), pH value of nanoemulsion, and NaCl or CaCl2 electrolytes on the demulsification efficiency (RO) were investigated. The RO of Fe3O4@ODPA samples was found to be higher than that of bare Fe3O4 samples (S0, ST, and SN) under all CS values. With the increase in CS, the RO of Fe3O4@ODPA samples initially increased and then approached equilibrium value at Cs = 80.0 g·L−1. A maximum RO of ~93% was achieved at CS = 100.0 g·L−1 for the Fe3O4@ODPA sample S2. The pH and two electrolytes had a minor effect on RO. The Fe3O4@ODPA nanoparticles maintained high RO even after being reused for demulsification 11 times. This indicates that the hydrophobic Fe3O4@ODPA samples can be used as an effective magnetite demulsifer for oil-in-water nanoemulsions.
