“…The presence of large H 2 bubbles significantly deteriorates the uniformity of the as-deposited coatings. A similar problem was reported in other investigations on the ePD of chitosan and chitosan/HA coatings, as described previously [29][30][31][32][33][34]. In the present work, a significant reduction in the formation of bubbles and thus better homogeneity of the coatings was obtained by using a solution of chitosan (0.5 g/l) in a mixture of distilled water and 1 vol.…”

“…The typical behaviour of current density as a function of deposition time is shown in figures 8a,b. The mechanism for the ePD of chitosan was described in detail in refs [14,[33][34][35]. According to these authors, positively charged chitosan molecules are prepared by protonation in the acetic acid solution and form cationic electrolytes, according to the following equation:…”

In this study, chitosan coatings were electrophoretically deposited (EPD) on near-β Ti-13Nb-13Zr alloy. The influence of colloidal solution composition and EPD parameters on the quality of chitosan coatings was investigated. It was established that the uniformity of as-deposited chitosan coatings is highly dependent on the chemical composition of the solution used for EPD, the pH, electrophoretic mobility and zeta potential of chitosan colloidal molecules, as well as EPD parameters, such as potential difference value and deposition time. The microstructure of the coatings was investigated using electron microscopy and X-ray diffractometry. The coatings 350 nm thick were homogeneous and exhibited an amorphous structure. The coatings had low hardness and Young’s modulus. The effect of surface of the substrate preparation prior to coating deposition on the adhesion of chitosan coatings to the Ti-13Nb-13Zr alloy was also investigated. The coatings exhibited good adhesion to the non-acid-etched surface of the titanium alloy.

“…In addition, no ibuprofen peaks were found in Fig. 3, one reason might be that the ibuprofen were completely covered by PCL in the process of spraying and the other reason is that the absorption intensity is proportional to the concentration and small volume fraction of ibuprofen was difficult to be detected within the sensitivity limit of XRD [34].

An Impact of the Recent Developments in Coating Materials and Techniques on the Corrosion Response of AZ91D Alloy: A Review

et al. 2023

View full text Add to dashboard Cite

AZ91D, a die‐casted alloy, offers several benefits (better saltwater corrosion resistance, suitable castability, and good atmospheric stability) over other grades of magnesium alloy. However, it cannot overcome the challenging requirements of advanced applications in its current form. Extensive research in coating technologies is crucial in enhancing the performance of AZ91D alloy in highly corrosive environments (coastal and marine, industrial, farm, etc.). The high corrosion resistance of AZ91D for various applications is achievable through the deposition of different materials. Developments in coating materials and techniques, with their influence on the corrosion protection behavior of AZ91D alloy, over the last decade (2012–2022), are focused on in this study. It is observed that composite, biodegradable, and self‐healing coatings are gaining popularity. The transition in the coating technology, from conventional to self‐healing coating materials and from conventional to environment‐friendly coating techniques, is a vital part of this discussion. This review further explores how different additives, pre‐treatments, post‐treatments, and corrosion inhibitors affect the corrosion performance of coatings. This study helps select the optimum coating material for AZ91D magnesium alloy to fulfil a specific application requirement and guides toward technological developments in this segment.
