“…The main limitation of their use is the ability to disintegrate under long mechanical effects (friction, erosion, etc.) [[7], [8], [9]]. Stainless steel alloys are characterized by high strength and low cost, for example, compared to cobalt-chromium and titanium alloys.…”

The current research is devoted to the study of the modification of the titanium implants by the micro-arc oxidation with bioactive calcium phosphate coatings containing Ag or Sr and Si elements. The coatings’ microstructure, phase composition, morphology, physicochemical and biological properties were examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). Ag-containing and Sr-Si-incorporated coatings were formed in alkaline and acid electrolytes, respectively. The formation of the coatings occurred at different ranges of the applied voltages, which led to the significant difference in the coatings properties. The trace elements Ag, Sr and Si participated intensively in the plasma-chemical reactions of the micro-arc coatings formation. Ag-containing coatings demonstrated strong antibacterial effect against Staphylococcus aureus AТСС 6538-P. MTT in vitro test with 3T3-L1 fibroblasts showed no cytotoxicity appearance on Sr-Si-incorporated coatings.

“…2, together with the coefficient of friction (COF) values recorded during the sliding and the wear track morphologies for the untreated alloy and Ni-P coated sample and corresponding Al 2 O 3 counter parts generated after generated after the sliding. Before sliding, the OCP values were stable in all samples due to the presence of a passive film on the sample surfaces in contact with the electrolyte [5]. In the untreated alloy, when the sliding started, OCP values dropped down sharply, it means that the passive film becomes fully destroyed in presence of 3.5 wt% NaCl solution under a high load of 10 N. During the sliding, the untreated alloy presented more negative OCP when compared to the Ni-P coated sample (Fig.…”

Electroless NiP coating was deposited on an AA7075 aluminum (Al) alloy, and its morphology, microhardness and tribocorrosion behaviour were evaluated. Coating characterization was done using light optic microscope (LOM) and field emission gun scanning electron microscope (FEG-SEM). Tribocorrosion tests were performed under open circuit potential (OCP) using a reciprocating ball-on-plate tribometer where a 10 mm diameter alumina ball was used as counter material and a normal load of 10 N was applied during 45 min. The NiP coating's microhardness and tribocorrosion performance were higher than untreated alloy.

Oral rehabilitation devices are susceptible to bio-tribocorrosion phenomena in the oral environment due to the synergism of wear, chemical, biochemical, and microbiological processes. This review summarizes the clinical problems and advances obtained based on current scientific evidence as well as the influence of tribological fundamentals, testing methodologies, and protocols in tribocorrosion analyses. The main clinical question related to oral rehabilitation with dental implants is the treatment failure, which is influenced by material degradation. Titanium-based implants are exposed to wear and corrosion challenges in the oral environment since the implantation and along the lifetime service. The titanium (Ti) properties such as structural material, connection design, surface treatments, alloying elements are influencing factors for material behavior. In addition, wear-corrosion factors such as cyclic loads, micromovements, oral biofilm, decontamination methods are also associated with dental implants degradation. These environmental conditions to which dental implants are submitted leads to the release of Ti particles and ions with cytotoxic and harmful effects on peri-implant surrounding tissues. In this context, the current state of the art of bio-tribocorrosion over the last decade has been steadily increasing to understand material degradation. The basic test system used to translate the tribocorrosion phenomena in the oral environment to the bench consists of electrochemical and tribological synergic analysis. The mechanical (applied load, frequency, stroke distance, and number of cycles) and electrochemical (solution composition, concentration of anions, and pH) test conditions are determinants for materials tribocorrosion performance. To overcome the tribocorrosion phenomena some strategies have been used such as alloying elements for Ti-alloys manufacture, surface treatments, and biomolecules immobilization. Further studies need to have the tribocorrosion analyses as the basis for new smart materials development considering the importance of such aspects for the biomaterial clinical behavior. Finally, tribological tests are relevant strategies for understanding the mechanisms of degradation in the oral environment and for providing a way to improve the clinical outcomes of dental implants.
