Special Issue Information

Dear Colleagues,

The surface engineering of metallic biomaterials is driven by the need to enhance performance in long-term implantation in medical applications. Considering that the healthcare industry continues to grow, there is an ongoing demand for developing advanced materials that meet the specific requirements of biomedical implants and devices. One of the key points is devoted to improved corrosion, wear resistance, and mechanical properties, which are directly linked to the durability and reliability of metallic biomaterials. In this scenario, there are innovative tools to achieve these goals, employing surface modification and metallurgical processes. There is a special focus on guaranteeing the superior biocompatibility of metallic surfaces, with proper integration with biological tissues without risk of adverse reactions. Furthermore, novel multifunctional surfaces have demonstrated benefits in antimicrobial properties and drug delivery ability. Lastly, integrating advanced manufacturing techniques has allowed the customization and optimization of metallic biomaterials to attenuate the stress-shielding effect, provide proper biomechanical support, and enhance corrosion and wear resistance. Overall, the demands for the surface engineering and properties of metallic biomaterials are centered around creating innovative solutions that can improve patient outcomes and advance the field of biomedical engineering.

In this Special Issue, we welcome articles that focus on developing and characterizing novel metallic biomaterials with functionalized surfaces and coatings, and that exhibit enhanced mechanical, corrosion, and wear properties, biocompatibility, and bioactivity.

Titanium has specific uses due to its cost, which is counterbalanced by its extraordinary chemical and physical properties. Submarine hulls and nuclear power plant pipes have been made of titanium since the last century due to its high corrosion resistance, and the aircraft industry has also exploited its remarkable properties, such as lightness and high melting point. Surface modifications by plasma electrolytic oxidation (PEO) may increase its corrosion resistance, roughness and wettability. Furthermore, greater corrosion resistance is a rather attractive property in nuclear power plant pipes, although the increased roughness and wettability are disadvantageous downsides as they favor the attachment of marine organisms. Nonetheless these new features are particularly interesting for biomedical applications. In this study, PEO films were produced on commercially pure titanium substrates using different electrolytes, one of which contains zirconium dioxide and the other consisting of tantalum pentoxide, in addition to a third one composed of a combination of the former two. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analyses were performed in addition to contact angle and roughness measurements, and electrochemical tests were carried out to comparatively characterize the different film compositions. The results revealed that excellent corrosion resistance was achieved by mixing oxides in the electrolyte. Full article
