“…Surface dealing by a biocompatible nano-composite coating were accomplished to significantly enhance the wear and corrosion resistance of the alloy by using numerous coating techniques such as sol gel method. This nano-composite coating has effects on the reactivity of the alloy surface, the biochemical reactions in the human body and the alloy surface properties [5].…”

T HIS paper dealt with two newly done nano-composite films, the first composed of chitosan nanoparticles (CNP) and the second composed of chitosan nanoparticles modified with silver nanoparticles (CNP+SNP), each one is coated on bare Ti alloy surface. Electrochemical impedance spectroscopy (EIS) and Tafel tests were accomplished to identify the corrosion behavior of the bare Ti alloy surface and the synthesized nano-composite coatings on titanium alloy surface in artificial saliva solution. The morphology of the alloy surface coating was achieved. Besides that, the antibacterial activity for the nano-coatings was examined and linked with the bare Ti alloy. The overall results showed that both the two novel coatings enhance the corrosion protection and the antibacterial activity of the studied alloy, where the corrosion resistance and the antibacterial activity of (CNP+SNP) nano-composite coating is remarkably greater than CNP coating.

“…Finally, these droplets were launched against the substrate (at a speed in excess of 400 m/s) which resulted in the liquid coating. The coating was flattened and experienced partial elastic recoil at the moment of impact, subsequently solidifying to form the lamellar microstructure 15 .…”

Ti-6Al-4V alloy is employed in implants because of its good mechanical strength, excellent biocompatibility, and good resistance to corrosion in biological environments. Herein, a composite (HAp-TiO 2 , 50% by volume of both components) coating surface employing Ti-6Al-4V was characterized. Samples were analyzed post fabrication and post heat treatment to analyze the coating recrystallization, phases, crystallinity, porosity, and roughness. The coating showed rutile crystalline and amorphous Hap phases with crystallinity, porosity, and roughness of 55.6%, 13.6 ± 1.0%, and 4.2 ± 0.6 µm; whereas, after heat treatment, it showed a rutile hydroxyapatite phase and β-TCP with values 75.6%, 13.9 ± 1.9%, and 3.8 ± 0.2 µm, respectively. The composite exhibited 874 ± 26 HV 100 hardness and 30 ± 2 MPa adhesion strength after heat treatment, which agree with previously reported data on other bioactive coatings. Therefore, this composite becomes much more crystalline after heating at 750 °C for 1 h.

“…Several studies exist that test the electrochemical behavior of metallic biomaterials in SBF and cell culture media . Comparative data found in the literature between SBF and DMEM mostly focus on either a limited number of metallic materials/coatings or precipitation of various products on the surface upon immersion for long periods of time . Besides this, the influence of proteins on the corrosion mechanisms and kinetics seems to be an ongoing debate in the available literature .…”

Corrosion behavior is an important parameter for metallic biomaterials used in the body environment. To mimic bodily fluids, simulated body fluid (SBF) has been used extensively. Even though many studies focus on corrosion inside SBF, SBF has a very time consuming and delicate preparation procedure and contains no essential and organic components for the cell environment, which may affect corrosion kinetics. We aimed to investigate whether corrosion behavior or kinetics change in different solutions, SBF and Dulbecco's modified Eagle medium (DMEM). For this purpose, five commonly used metallic biomaterials, AISI 316 stainless steel, CoCrMo alloy, CP‐Ti, Ti6Al4V, and Ti6Al7Nb were subjected to open circuit measurements, cyclic polarization, and electrochemical impedance spectroscopy. Quantitative analyses were performed and surface topography was investigated via scanning electron microscope and a roughness tester. We observed that the materials exhibited similar behaviors in SBF and DMEM but the corrosion kinetics were somewhat different and the results obtained from DMEM were time dependent.
