“…This is confirmed by the obtained results for C1 when compared to TiO 2 and Ti-6Al-4V surfaces. The finding corrosion parameters are in the same order of magnitude and in good agreement with literature [10], [27][28][29][30]. 6.…”

“…Reviewed literatures showed some controversy about the selected equivalent circuit (EC) modeling the electrochemical behavior of Ti-6Al-4V alloy in Hank's solution at 37°C. However, all of them [27,[28][29][30][31][32][33][34][35], agree that there was evidence of the formation of a twolayer oxide film (essentially TiO 2 [35]) composed of dense inner layer and porous outer layer. In this case, the EC model consists with Hank's solution resistance R s .…”

Multilayered and nanostructured coatings of Ti based alloys (oxides and nitrides) are elaborated and tested for increasing protective properties such as corrosion and wear resistances. A pin-on-disc tribometer was used to evaluate the wear resistance in Hank's solution against bovine bone. Corrosion behavior in Hank's solution was determined by potentiodynamic and electrochemical impedance spectroscopy techniques. Besides, the specimen surfaces were characterized by Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) microanalyses. The results showed that optimal tribological properties were obtained in the case of coatings having TiN as top layer. The main wear mechanism was abrasive third body wear. In vitro corrosion tests at 37°C showed that the better corrosion resistance was obtained when TiN was the top layer. However all of them exhibited good tribological properties, good corrosion resistance and then may be promising options for biomedical applications.

“…At the nano level, the control of inflammation and the speed of bone formation are related to the absorption at the surface (0 nm) of biomolecules from the blood. In the first minutes of the implantation, there is clear evidence that the proteins and other biomolecules will be guided essentially by the chemical content of the implant’s outermost layer (0 nm) [ 27 , 52 , 53 , 54 ].…”

Nanoscale Chemical Surface Analyses of Recycled Powder for Direct Metal Powder Bed Fusion Ti-6Al-4V Root Analog Dental Implant: An X-ray Photoelectron Spectroscopy Study

Over the past couple of decades, additive manufacturing and the use of root-analogue-printed titanium dental implants have been developed. Not all powder particles are sintered into the final product during the additive manufacturing process. Reuse of the remaining powder could reduce the overall implant manufacturing cost. However, Ti-6Al-4V powder particles are affected by heat, mechanical factors, and oxidization during the powder bed fusion manufacturing process. Degradation of the powder may harm the final surface composition and decrease the biocompatibility and survival of the implant. The uncertainty of the recycled powder properties prevents implant fabrication facilities from reusing the powder. This study investigates the chemical composition of controlled, clean, and recycled titanium alloy powder and root-analogue implants (RAI) manufactured from these powders at three different depths. The change in titanium’s quantity, oxidization state, and chemical composition in powder and RAI implants have been demonstrated and analyzed. While not identical, the surface chemical composition of the recycled powder implant and the implant manufactured from unused powder are similar. The results also indicate the presence of TiO2 on all surfaces. Many studies confirmed that titanium dioxide on the implant’s surface correlates with better osteointegration, reduced bacterial infection, and increased corrosion resistance. Considering economic and environmental aspects, surface chemical composition comparison of clean and reused powder is crucial for the future manufacturing of cost-effective and biocompatible implants.

“…Body fluids also contain amino acids and proteins, which have been shown to hasten corrosion. [52][53][54][55][56] Because the bodily fluids operate as buffers, the pH varies very little. Normal blood and interstitial fluid have a pH of 7.35-7.45.…”

There are several enviable attributes of titanium and its alloys that contribute to their popularity in biomedical devices and equipment, including their rather low modulus, excellent corrosion resistance, and biocompatibility, good machinability, formability, and strength comprehensive impact and fatigue. Nevertheless, titanium and its alloys do not meet all medical requirements due to its unique properties and alloys, so surface modifications must be made to enhance mechanical, chemical, and biological characteristics. As a review of biomedical engineering, this article discusses specific polymers for coating applications as well as various polymer coatings for functionalization improvements. The versatility of biopolymer coatings makes them extremely appropriate for a broad range of biological uses. To enhance the engineering of tissue and drug delivery, this study summarized and analyzed the most recent advances in biopolymer coatings. Surface qualities of polymer coatings can be adjusted to meet specific criteria for various biomedical applications or integrated with new capabilities. Moreover, polymer coatings containing different inorganic ions can enhance the growth of tissue, proliferation of cells, healing, as well as the transfer of biomolecules, like active molecules, agents of antimicrobial, factors of growth, and medications.Highlights Surface modification avenues of Ti materials as orthopedic replacements are critically reviewed. Basic descriptions of titanium and titanium alloys are presented. Advances in the corrosion behavior of biomedical titanium alloys are thoroughly scrutinized. Fundamental methods based on mechanical, physical, and chemical principles for biopolymer coatings are particularly presented. Main biopolymer coatings types that are used on titanium surfaces are reviewed.
