“…The encapsulation of corrosion inhibitors and the introduction of the capsules into the matrix of the coating are considered to be a viable way of avoiding the above disadvantages [27]. There are literature reports corroborating the more beneficial effect of inhibitor encapsulation on the quality of coatings in comparison with the cases in which an inhibitor is added directly to the coating [28]. A major advantage of such coatings is the controlled release of the capsules' content and the widely adjustable self-repair properties.…”

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.

“…The steady state condition might be due to the lack of variation in the interface composition. By comparing the OCP values obtained for all the specimens it can be observed that the OCP value of Mg-10 wt.% Gd shifted to a noble potential value by at least 0.6 V. This increase of OCP suggests a reduction of susceptibility of the alloy to the corrosion process but the OCP values do not provide any information on the corrosion kinetics [33]. That is to say that the Mg-alloy interfaces immersed in 1 wt.% NaCl solution probably undergo formation of a magnesium hydroxide film wherein the adsorbed Cl -ions do not reduce the effectiveness of the protective film.…”

The aim of this work was to study the effect of gadolinium content on the corrosion behavior of magnesium alloys in 1 wt.% NaCl solution at 21.5 (±0.5) °C. Four Mg-Gd alloys, namely Mg-2 wt.% Gd, Mg-5 wt.% Gd, Mg-10 wt.% Gd, and Mg-15 wt.% Gd, were studied. Weight loss measurements, potentiodynamic tests, electrochemical impedance spectroscopy, XR diffraction, and scanning electron microscopy combined with energy-dispersive X-ray spectroscopy (SEM-EDS) were performed on the four Mg-Gd samples. The results showed the influence of the Gd content on the corrosion behavior of these alloys in 1wt.% NaCl solution. The corrosion resistance of the Mg-Gd alloys was improved with the introduction of 10 wt.% Gd in Mg matrix. Thus, weight loss and electrochemical measurements revealed the better corrosion resistance for Mg-10 wt.% Gd alloy. Further addition of Gd exceeding 10 wt.% in a magnesium matrix reduces the corrosion resistance of Mg-alloy and induces an incremental increase in the corrosion rate.

“…Earlier several types of coating techniques like anodizing, electrochemical plating, chemical conversion, hybrid organic coating etc. have been applied on Mg and their alloys [4][5][6][7][8][9][10][11][12][13][14][15]. However, each method is having their own advantages and disadvantages.…”

This investigation describes the potential of sol-gel derived alumina coating on the corrosion resistance of magnesium metal in 3.5 % NaCl solution. Coating deposition was performed by dip coating technique using boehmite (AlOOH) sol followed by their sintering at 250°C. EDX and FTIR analysis confirmed that alumina is a main constituent of the coating. Microstructural examination of the coated surface demonstrated amorphous nature of coating of 2-3 lm in thickness. Potentiodynamic polarization and electrochemical impedance measurements indicated a considerable improvement in the corrosion resistance of the coated substrates.
