“…The features of a spacing parameter are depended on the number of peaks and valleys regions. Some pores, scratches and small dimples presence on the surface; this can be attributed to the some defects that probably originate from random heterogeneity of the material as observed by Petr Vlcak et al when they study the morphology of Ti-Nb-Zr-Ta alloy by AFM [17].…”

Corrosion behavior and wear resistance were investigated for three prepared alloys (Ti-18Nb-xCu) by powder metallurgy method with adding three weight percents of Cu (5, 7 and 9 wt %). The wear results show that Ti-18Nb-7Cu alloy has the lowest wear rate due to hard Ti2Cu phase which mostly formed in the percent of 7%Cu. While the corrosion behavior was different due to the variation in formed cathodic and anodic sites and the formed phase led to increasing the formation of micro-galvanic cells on the alloys surface. AFM analysis was applied to show the surface topography and measure surface roughness, the results indicated that Ti alloy with 7% Cu had the highest surface roughness.

“…On the treated Zr sample, only zirconium oxides were detected. The zirconium (Zr 3d 5/2) nitride peak should be detected at an energy of 180.9 eV [ 17 ]. In numerous works [ 22 , 23 , 24 , 25 , 26 , 27 ], zirconium alloys were treated by nitrogen ion implantation at higher temperatures than in our work, usually between 300 °C and 800 °C, and had successfully detected zirconium nitride on their samples.…”

Titanium beta alloys represent the new generation of materials for the manufacturing of joint implants. Their Young’s modulus is lower and thus closer to the bone tissue compared to commonly used alloys. The surface tribological properties of these materials should be improved by ion implantation. The influence of this surface treatment on corrosion behaviour is unknown. The surface of Ti-36Nb-6Ta, Ti-36Nb-4Zr, and Ti‑39Nb titanium β-alloys was modified using nitrogen ion implantation. X-ray photoelectron spectroscopy was used for surface analysis, which showed the presence of titanium, niobium, and tantalum nitrides in the treated samples and the elimination of less stable oxides. Electrochemical methods, electrochemical impedance spectra, polarisation resistance, and Mott–Schottky plot were measured in a physiological saline solution. The results of the measurements showed that ion implantation does not have a significant negative effect on the corrosion behaviour of the material. The best results of the alloys investigated were achieved by the Ti-36Nb-6Ta alloy. The combination of niobium and tantalum nitrides had a positive effect on the corrosion resistance of this alloy. After surface treatment, the polarization resistance of this alloy increased, 2.3 × 106 Ω·cm2, demonstrating higher corrosion resistance of the alloy. These results were also supported by the results of electrochemical impedance spectroscopy.

“…Potentiodynamic polarization curves were measured from À 1.0 V to 1.0 V (versus saturated calomel electrode) in the anodic direction with a scan rate of 1 mV/s. These similar or narrower potential ranges of potentiodynamic tests were usually used for the determination of corrosion performances of metal materials [26][27][28]. Corrosion parameters, including corrosion potential and corrosion current density extracted from potentiodynamic polarization curves, were used to evaluate the corrosion resistance in a simulated body fluid, Ringer's solution.…”

The Ti‐30Zr‐5Al‐3V titanium alloy has an ultra‐low Young's modulus. So, it promises great application potential as a hard‐tissue implanted biomaterial. However, its surface performances need to be improved before clinical applications. In this work, a carbonated hydroxyapatite film is deposited on the surface of Ti‐30Zr‐5Al‐3V bio‐alloy using electrochemical methods. Microstructure, film‐substrate adhesion, and electrochemical corrosion behavior of carbonated hydroxyapatite deposited specimens in Ringer's solution are investigated. A homogeneous, dense, and fully covered carbonated hydroxyapatite film forms on the surface after depositing at 3 V, 90 °C for 120 minutes. The formation mechanism of the carbonated hydroxyapatite film on the micro‐nano structure surface is revealed. The corrosion performance of carbonated hydroxyapatite deposited specimens in Ringer's solution is evaluated by using potentiodynamic polarization curves. The carbonated hydroxyapatite deposition obviously enhanced the corrosion resistance of the Ti‐30Zr‐5Al‐3V bio‐alloy.
