Summary: In this study, zein coatings were successfully obtained on titanium substrates by electrophoretic deposition, with the coating morphology being significantly influenced by the zein content, water to ethanol ratio, process voltage, and time. Chemical treatment of the Ti substrate surface prior to deposition was found to enhance the adhesion of the coatings. Coated titanium substrates exhibited slightly lower electrochemical corrosion resistance in aqueous solution compared to uncoated substrates, and showed well-developed surface topography and hydrophilic nature.

Summary: Bioceramic coatings on metallic implants provide wear-resistance and biocompatibility, and can develop bone-like apatite in physiological environments. Radio frequency magnetron sputtering (RFMS) is a technique used to deposit these coatings, with features such as chemical composition stability and excellent surface finish. However, it requires high-temperature operation and annealing. RFMS has the potential to develop multifunctional coatings and has been used in the field of bioceramic coatings.
