Summary: This study focuses on the development of calcium phosphate/nano-sized silica composite coatings using one-step electrochemical deposition combined with ultrasonic irradiation. Various analytical techniques were employed to evaluate the morphology and composition of the coatings, as well as their in vitro performance. The results showed that the presence of nano-sized silica particles had a positive impact on surface morphology and cell adhesion and proliferation.

Summary: Poly(methyl methacrylate) (PMMA)-silica coatings modified with calcium phosphates (CaPs) were developed to enhance the corrosion resistance and bioactivity of Ti6Al4V titanium alloys for medical and dental implants. The addition of hydroxyapatite (HA) and beta-tricalcium phosphate (beta-TCP) improved the thermal stability and hydrophilicity of the coatings, contributing to effective osteointegration. The modified coatings exhibited high anti-corrosion efficiency and remained stable in simulated body fluid (SBF) solution after 150 days of exposure.

Summary: The nickel/graphene oxide composite coatings produced by electrodeposition showed optimal characteristics with 0.1 wt.% GO content, providing greater surface homogeneity and lower roughness. The incorporation of GO up to 0.1 wt.% also increased the electrochemical corrosion resistance and thermomechanical behavior of the coatings.

Summary: A microbial green surfactant was used to facilitate the deposition of brushite and hydroxyapatite coatings on stainless steel. The addition of the surfactant affected the composition and morphology of the coatings. The surfactant inhibited the growth of hydroxyapatite and resulted in well-defined flower-like coatings. The addition of the surfactant also improved the corrosion resistance, degradation, antibacterial properties, and hemocompatibility of the coatings.

Summary: This study used reverse pulse plating technique to investigate the impact of different surfactants on the incorporation of SiC nanoparticles in the Sn matrix in electrolytes. The results showed that the type of surfactants affected the incorporation of SiC in Sn coating, with cationic surfactant leading to maximum grain refinement and anionic surfactant resulting in the minimum resistivity. Additionally, non-ionic surfactants displayed superior corrosion protection ability compared to other surfactants used in this study.

Summary: Titanium alloys are widely used in marine applications due to their low density and high specific strength, but wear and corrosion of components remains an issue. Protective coatings, such as CrMoCN, have been studied to alleviate this problem. The influence of Mo content on the protective performance of CrMoCN coating for Ti-6Al-4V substrate has been investigated, showing that higher Mo content leads to better wear- and corrosion-resistances.

Summary: This study investigated the tribological and corrosion performances of as-deposited and annealed CrN/CrAlN multilayer coatings on 304 stainless steel substrates deposited by cathodic arc evaporation process. The results showed that annealing led to the decomposition of CrN into Cr2N. Additionally, the surface roughness and wettability of the annealed samples increased as the annealing temperature increased. The hardness decreased due to the increase in crystallite size. The sample annealed at 400 degrees C exhibited the lowest wear rate and the specimen annealed at 700 degrees C showed the highest corrosion resistance.

Summary: An anticorrosive CaCO3/MgO coating was rapidly electrochemically deposited on AZ41 Mg alloy for concrete formwork. Surface characterizations revealed a dual-layer structure consisting of outer CaCO3 layer and compact inner MgO layer. The pretreatment of the electrochemical deposition electrolyte contributed to the formation of a dense coating and enhanced the binding between the layers, resulting in improved anticorrosion property. The corrosion mechanism of the CaCO3/MgO coating was suggested and discussed.
