“…After N−PIII, a layer of modified layer mainly containing TiN was synthesized on the surface of Ti. Because of excellent chemical stability and corrosion resistance of TiN, 27 Ti surface had better corrosion resistance after N−PIII.…”

“…The standard electrode potential of Ti is lower than that of Cu, 26 thus Cu/Ti galvanic corrosion is easy to form on the surface of Cu−Ti, in which Ti acts as anode preferentially, and Cu acts as a cathode to cause a hydrogen evolution reaction. For N/Cu−Ti, because of the stable chemical property of TiN, 27 Cu on the surface of N/Cu−Ti tends to act as an anode and releases copper ions, whereas TiN acts as a cathode. Therefore, the surface of N/Cu−Ti releases more copper ions than that of Cu−Ti.…”

“…Therefore, the other element can be implanted to the surface of titanium with copper for improving the mechanical property. Titanium nitride produced by nitrogen ion implantation (N–PIII) is generally utilized to modify the titanium surface because of its excellent mechanical property, corrosion resistance. − …”

Titanium and its alloys have been commonly used as implant materials. However, the inherent bioinert nature hinders its good osseointegration which limits its permanent clinical applications. In this work, nitrogen (N) and copper (Cu) dual ions were implanted into titanium by plasma immersion ion implantation and deposition (PIII&D) technology. The corrosion resistance, mechanical property, antibacterial ability, and angiogenic activity of the modified titanium surfaces were investigated. Experimental results show that titanium nitride (TiN) film embedded with Cu nanoparticles (Cu NPs) forms on the surface of the N/Cu dual ions implanted titanium. The N/Cu dual ions implanted titanium exhibits excellent corrosion resistance and mechanical property. The galvanic corrosion of Cu/TiN can effectively control copper ion release to enhance the antibacterial and angiogenic performances of the Ti surface.

It has been established that nitrogen implantation can modify metals surface properties such as corrosion, wear, friction, etc. Recent studies have shown that nitrogen implantation into titanium and its alloys leads to the formation of titanium nitride, which has interesting biological, chemical, and mechanical properties. In the present investigation, commercially pure biocompatible titanium implanted by nitrogen. Implantation of ions performed at 80 keV and a dose of 2.1 × 10 ions/cm at four different temperatures of 300, 473, 673 and 873 k. Phase and chemical compositions of modified surfaces after implantation obtained using grazing incidence X-ray diffraction technique (GIXRD) and Fourier transform infrared spectrum (FTIR), respectively. The roughness variations before and after ion implantation were observed by atomic force microscopy (AFM). Electrochemical behavior of the samples was investigated in Ringer solution by using electrochemical impedance spectroscopy and polarization tests. Scanning electron microscopy micrographs was used to evaluate the surface morphology of the samples. Variation of the Young's modulus and hardness of samples were examined using nano-indentation technique before and after ion implantation. Compared to nano-hardness of unimplanted sample, the maximum nano-hardness value of implanted samples is as high as 14.2 GPa, which is at least eight times larger than hardness of the unimplanted sample. The elastic modulus of unimplanted sample was obtained 106 GPa and the maximum elastic modulus value of implanted samples is as high as 178 GPa. Corrosion test results showed that implantation could increase the corrosion resistance of samples, but by increasing the implantation temperature, the corrosion resistance will decrease.
