“…Unfortunately, the long-term use of NiTi alloy implants necessitates the improvement of their corrosion resistance and biocompatibility [5][6][7]. This goal might be achieved by modifying the alloy surface by protective coatings made of ceramics [8][9][10][11], polymers [12], metals [13], diamond-like carbon-DLC [14], or complex composite layers [15][16][17][18].…”

“…Moreover, pure apatite might be prone to form a microbial biofilm on its surface, which favors the development of various infections [19][20][21][22][23][24]. Calcium phosphates-based ceramic is frequently used to produce coatings on metallic implants, including NiTi alloys, by various surface modification methods [10,11,[25][26][27][28].…”

“…Extending the aging time results in the formation of the Ni 3 Ti 2 phase with a simultaneous dissolution of the Ni 4 Ti 3 particles, followed by the precipitation of the equilibrium Ni 3 Ti phase particles. Consequently, the decomposition of the B2 parent phase influences the shape memory and the superelasticity effect [1,10,11,39,40]. One of the interesting methods for modifying the surface seems to be electrophoretic deposition (EPD) [41][42][43][44][45].…”

The surface modification of NiTi shape memory alloys is a method for increasing their multi-functionalities. In our solution, hydroxyapatite powder was mixed with a chemically synthesized silicon dioxide/silver (nSiO2/Ag) nanocomposite in a different weight ratio between components (1:1, 5:1, and 10:1) and then electrophoretically deposited on the surface of the NiTi alloy, under various time and voltage conditions. Subsequently, uniform layers were subjected to heat treatment at 700 °C for 2 h in an argon atmosphere to improve the strength of their adhesion to the NiTi substrate. A change in linear dimensions of the co-deposited materials during the sintering process was also analyzed. After the heat treatment, XRD, Raman, and Scanning Electron Microscopy (SEM) + Energy Dispersive Spectrometer (EDS) studies revealed the formation of completely new composite coatings, which consisted of rutile and TiO2-SiO2 glass with silver oxide and HAp particles that were embedded into such coatings. It was found that spalling characterized the 1:1 ratio coating, while the others were crack-free, well-adhered, and capable of deformation to 3.5%. Coatings with a higher concentration of nanocomposite were rougher. Electrochemical impedance spectroscopy (EIS) tests in Ringer’s solution revealed the capacitive behavior of the material with high corrosion resistance. The kinetics and susceptibility to pitting corrosion was the highest for the NiTi electrode that was coated with a 5:1 ratio HAp/nSiO2/Ag hybrid coating.

“…NiTi alloy with all its advantages can cause cytotoxicity and consequently necrosis of the tissues adjacent to the implant, which is due to the release of the toxic nickel ions from the surface . Applying the bioceramic coatings on the bioinert NiTi alloy is a common approach to reduce the release of nickel ions that simultaneously improves the bioactivity of the surface . In this respect, HA bioceramic is of great importance due to its appropriate biocompatibility, bioactivity, and high stability in the body .…”

In this study, the hydroxyapatite (HA)‐titanium (Ti, 20 wt.%) multiwalled carbon nanotubes (MWCNTs, 1 wt.%) composite coating was applied on the NiTi alloy by using the electrophoretic deposition (EPD) technique. The morphologies and the phase structures of the coatings were investigated by the FESEM and XRD analysis, respectively. The corrosion behaviors of the coated NiTi samples were investigated using the polarization and electrochemical impedance spectroscopy tests in a simulated body fluid (SBF). The amounts of the released Ni ions from the coated NiTi were studied in the SBF. The results of the electrochemical tests revealed the corrosion resistance of the NiTi coated with HA was further improved by the addition of the Ti and MWCNTs to the HA coating. The current density and corrosion resistance of the NiTi alloy changed from 2.52 μA.cm−2 and 24.13 kΩ to 0.91 nA.cm−2 and 5.92 MΩ after coated with the HA‐Ti‐MWCNTs composite coating. Also, the number of nickel ions released from the surface of the NiTi alloy to the SBF medium suppressed from 11.8 to 0.08 μgr.L−1, after coating with HA‐Ti‐MWCNTs. Also, the cellular proliferation in the culture medium consisting of the NiTi alloy coated with the HA‐Ti‐MWCNTs improved significantly (compared with that of the NiTi alloy) as shown no toxicity in the cell culture medium.

Zinc (Zn) and its alloys have recently gained research interest due to their good biosafety, biological function, biodegradability, and formability. Zincphosphate (ZnP) coating has been shown to improve the corrosion resistance and biocompatibility of Zn alloys. Here, a biodegradable ZnP-coating on Zn1Cu0.1Ti (ZCT) membrane with high strength-ductility and mechanical stability, suitable degradation rate, effective antibacterial ability, excellent in vitro and in vivo cytocompatibility, and osteogenesis is reported. The ZnPcoated ZCT exhibits high strength-ductility with a yield strength of 264 MPa, ultimate tensile strength of 312 MPa, elongation of 36.0%, and high mechanical stability before and after 30 d immersion in Hanks' and AS solutions, all of which are higher than those of ZCT. The ZnP coating shows good deformation resistance, healing effect, and bond strength with the substrate, meeting the clinical contour shaping requirements. The ZnP-coated ZCT membrane sample shows higher cell viability toward MC3T3-E1 and MG-63 cells, osteogenic and mitochondrial quality-control properties in vitro than those of the ZCT sample. Using a rat calvarial defect model, the ZnP-coated ZCT membrane shows complete biosafety and considerable osteogenesis performance. Overall, the ZnP-coated ZCT membrane is recommended as a promising biodegradable implant material for oral guided bone regeneration application.
