Summary: In this study, electrochemical reduction of ionic species during manganese deposition from sulphated aqueous solutions was investigated using two anionic exchange membranes. The research involved thermodynamic analysis, voltammetries, and chronopotentiometries to determine the reaction mechanism. Results showed that elemental selenium affects hydrogen evolution and leads to the formation of elemental sulphur by reducing sulphate ions with both membranes. Additionally, electrodeposition of metallic manganese was observed to begin in the range of -25 to -50 A m(-2) with minimal interference from parasitic reactions.

Summary: Fe-Mn alloys are potential materials for bioabsorbable implants like stents, with their composition and microstructure needing to be tailored for an adequate corrosion rate. Electrodeposition of Fe-Mn alloys yielded different microstructures and phases based on deposition potential and electrolyte composition. Increasing Mn content and maintaining a monophasic microstructure were achieved with higher NH4Cl concentration in the electrolyte. Despite challenges, these results demonstrate the feasibility of obtaining Fe-Mn bioabsorbable alloys by electrodeposition, offering a new processing route for these materials.

Summary: This study aimed to deposit high entropy alloy (HEA) coatings with five different elements from a single aqueous bath. The influence of pH, current density, and complex agent on the composition of deposited coating was examined. It was shown that pH had the most impact on the deposition of reluctant elements, while current density had the minimum effect. The deposited coating had a metallic, dense, and nodular morphology with configurational entropy of around 1.6 R.

Summary: The study investigates the formation patterns of Ni-ZrO2 and Ni-TiO2 composite coatings from methanesulfonate and sulfate electrolytes at pH 3. It is found that the aggregative stability of dispersed phase particles is higher in the methanesulfonate electrolyte. Therefore, the concentration of particles is higher in the methanesulfonate electrolyte, resulting in an increased content of non-metallic particles in composite coatings compared to sulfate electrolyte. A mechanism for forming composite coatings is proposed, taking into account the different rates of metal phase electrodeposition on electrode surfaces. A mathematical model is developed to describe the experimental data. The physicochemical properties of the composite coatings depend on the content of non-metallic phase particles, with increased microhardness and photocatalytic activity observed with higher dispersed phase content.

Summary: In this study, stainless steel material was coated with Ni-B alloy-based, TiC particle reinforced composite film using electrochemical deposition method. The effect of trimethylamine borane (TMAB) bath concentration on the properties of the obtained Ni-B/TiC nanocomposite coatings was investigated. The results showed that TMAB contributed to increasing the deposition rate and had a stronger effect at high TiC bath contents. The nanocomposite coatings exhibited significantly reduced crystal grain size and improved hardness compared to pure Ni coating. Moreover, the increase in TMAB bath concentration led to an improvement in corrosion resistance of the coatings.

Summary: Zinc oxide coatings with different morphologies were electrodeposited on Ti6Al4V substrates, and the incorporation of BG nanoparticles modified the spherical morphology of the coatings. The coatings with spherical morphology exhibited enhanced surface roughness, wettability, and adhesion strength, and showed complete barrier property after immersion in PBS solution. However, adverse effects were observed for the coatings with flower-like morphology at higher deposition voltage. The ZnO-BG composite coating with spherical morphology achieved the highest corrosion barrier performance and improved formation of Ca-P deposits on its surface during bioactivity tests in SBF.

Summary: Al2O3-TiO2 coatings were prepared using a silicate-based electrolyte and pulsed bipolar current in the PEO process. Nano-particle titania (NP-TiO2) and potassium titanyl oxalate (PTO) were used as Ti-based additive sources separately. The coatings were characterized using SEM, EDS, and XRD. Mechanical properties were investigated using nanoindentation and ball-on-disk tests. The results showed that PTO created a more compact inner layer with increased coating thickness, while NP-TiO2 formed a thinner but more compact inner layer with no effect on the outer layer morphology. XRD and Raman spectroscopy analyses indicated inert incorporation of NP-TiO2 into alumina, while reactive incorporation of TiO2 produced by PTO resulted in a polymeric titanium oxide structure with doped rutile and anatase phases. The Ti incorporation through PTO provided appropriate mechanical properties due to the more compact and thicker inner layer. The mechanism of PTO performance in the PEO process was discussed.
