“…As can be seen in the Figure 6 EDX analyses were taken on different zones of the AA2024 panel surface coated with 3V/epoxy system in order to determine the nature of the corrosion products ( Figure 8b). EDX spectrum of point 1 (Figure 8c) revealed the presence of aluminium, oxygen and chlorine ions, probably corresponding to typically Al(OH) 2 Cl and Al(OH)Cl 2 corrosion products reported elsewhere [12], and also due to the high size of the corrosion particles (also observed under the organic film). EDX spectrum of point 2 ( Figure 8d) corresponds mainly to aluminium alloy composition, with high concentrations of Al and Cu.…”

In the present study we compared the beneficial effect on the incorporation of modified silane nanocoating and conducting polymer additive to the adhesion and protection of aluminium surface with epoxy coating. Results proved that the protection imparted by the silane coating, suitably modified with phosphonic groups, showed an excellent adhesion to the metallic substrate as well as good adherence with the epoxy outer layer, which result in an improved corrosion resistance. The incorporation of 1% of poly (3-methyl thiophene acetate) (P3TMA) also improved the adhesion force of the epoxy paint adhered to the aluminium surface. However, the adhesion force decreased with the increase of the immersion time in NaCl 3.5% solution. In conclusion, both bilayer systems [vinyltrimethoxysilane (VTMS)/tetraethylorthosilicate (TEOS) and VTMS/TEOS/ ethylenediaminetetra(methylene phosphonic acid) (EDTPO)] and also the employment of P3TMA in the epoxy coating showed better results in accelerated corrosion assays, i.e. very low blistering formation was observed, compared with control samples based in a monolayer coating directly adhered to the aluminium surface.

“…In the case of silica-organic coatings, as the concentration of the silicate solution increases, their protective properties deteriorate due to high porosity. An improvement in their protective properties can be achieved through additional curing [103] or by applying a subcoating which by forming Si-O-M (M-a metal constituent of the substrate) bonds perfectly adheres to the substrate surface [104]. Curing is used to induce better cross-linking of the layer.…”

Self-healing coatings in anti-corrosion applications

2013

Nonmetallic (based on polymers or oxides) and metallic protective coatings are used to protect metal products against the harmful action of the corrosion environment. In recent years, self-healing coatings have been the subject of increasing interest. The ability of such coatings to self-repair local damage caused by external factors is a major factor contributing to their attractiveness. Polymer layers, silica-organic layers, conversion layers, metallic layers and ceramic layers, to mention but a few, are used as self-healing coatings. This paper presents the main kinds of self-healing coatings and explains their selfhealing mechanisms.

“…For S_WZ21 and BNS_WZ21, two distinct time constants can be observed in Figure 4b. The high-frequency regime time constant is generally attributed to the electrochemical response at the coatings/electrolyte interface [19,20,[43][44][45][46][47][48][49], whereas the time constant in the low-frequency regime is commonly attributed to the electrochemical response at the metal/electrolyte interface [19,20,[45][46][47][48][49][50][51]. The high-frequency regime time constant is much prominent in the case of BNS_WZ21.…”

Hexagonal Boron Nitride Impregnated Silane Composite Coating for Corrosion Resistance of Magnesium Alloys for Temporary Bioimplant Applications

Magnesium and its alloys are attractive potential materials for construction of biodegradable temporary implant devices. However, their rapid degradation in human body fluid before the desired service life is reached necessitate the application of suitable coatings. To this end, WZ21 magnesium alloy surface was modified by hexagonal boron nitride (hBN)-impregnated silane coating. The coating was chemically characterised by Raman spectroscopy. Potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) of the coated alloy in Hanks' solution showed a five-fold improvement in the corrosion resistance of the alloy due to the composite coating. Post-corrosion analyses corroborated the electrochemical data and provided a mechanistic insight of the improvement provided by the composite coating.
