“…Mo is desirable as an alloying element for the development of Ti-based biomaterials. Previous researches have studied the phase transformations and mechanical properties of different Ti-Mo alloys, and found that the phase constitutions, elastic modulus and hardness are different for Ti-Mo alloys with different Mo contents [3,4]. It is remarkable that the Ti-8Mo exhibits the highest mechanical properties among the porous Ti-(4-10 wt%)Mo alloys [2,5].…”

Abstract. In this study, the Ti-8Mo-6Ni alloys are subjected to add various amounts of NbC carbides as a strengthening phase after the sintering process. Meanwhile, the composite materials underwent a vacuum sintering process at different temperatures of 1175°C, 1225°C and 1275°C for 1 h, respectively. To evaluate the microstructure, mechanical properties and corrosion behaviors of the Ti-8Mo-6Ni alloys adding NbC via the vacuum sintering processes, tests on the relative density, hardness, transverse rupture strength (TRS), corrosion and microstructure inspections are performed using XRD and SEM, with the aim of improving the microstructure and properties of sintered Ti-8Mo-6Ni alloys. The experimental results showed that when 1 wt% of NbC carbides is added to the Ti-8Mo-6Ni alloys they possessed the optimal properties after sintering at 1275°C for 1 h. The sintering density increased to about 99.7%, the hardness is enhanced to 48.1 HRC and the TRS increased to 976 MPa. Meanwhile, the sintered composite materials possessed good corrosion resistance.

“…Thus, the formation of ω phase during cooling is suppressed in high β stable Ti-Mo alloy. 6,8) Zhao et al also found that ω phase is formed in the metastable β type alloys with different Mo contents and disappeared in Ti-Mo alloys with high Mo content. 13) Ti-Mo alloys are not always the most suitable for the particular purpose.…”

In this study, three different powders are mixed and used to produce Ti-8Mo-xNi alloys in three different proportions: Ti-8Mo-4Ni, Ti8Mo-6Ni and Ti-8Mo-8Ni. The Ti-Mo-Ni alloys simultaneously undergo various vacuum sintering temperatures of 1125, 1150, 1175 and 1200 C, respectively. The experimental results show that the Ti-8Mo-8Ni alloys acquire a higher sintering density (98.9%) and hardness (52.1 HRC) after sintering at 1175 C for 1 h. However, due to the grain growth and increased amount of nickel in the Ti-8Mo-8Ni alloys, the transverse rupture strength (TRS) shows an obvious decrease (as compared with Ti-8Mo-6Ni, the TRS value decreasing from 1177 to 685 MPa). Consequently, the suitable Ni content of the Ti-8Mo-6Ni alloys which proves advantageous to the TRS results from the uniform distribution of the TiNi intermetallic compound precipitates within the β matrix. The sintered Ti-8Mo-8Ni alloys also possess the lowest corrosion current (I corr = 1.87 × 10 −7 A·cm −2) and highest polarization resistance (56084 Ω·cm 2 ) in 3.5 mass% NaCl solutions. This result con rms that sintered Ti-8Mo-8Ni alloys effectively improve corrosion resistance.

Currently, the development of biomaterials has focused on having a low Young's modulus, biocompatibility, corrosion resistance, and antibacterial properties. Ti-Nb alloys have higher research value due to their excellent corrosion resistance and low Young's modulus. In recent years, the antibacterial properties of materials have been enhanced by the addition of Ag and Cu. Therefore, the corrosion resistance and antibacterial properties of the Ti-12Nb-1Ag alloy formulated in the current study were investigated and compared to those of commonly used Ti alloys, G2 pure Ti (ASTM B348 CP Grade 2), and Ti-6Al-4V, via electrochemical and E. coli antibacterial tests. Meanwhile, we also carried out a microstructural analysis to investigate the composition of the alloy. The results were as follows: (1) The electrochemical test demonstrated that Ti-12Nb-1Ag had a higher corrosion resistance than Ti-6Al-4V, which is similar to the properties of pure Ti. (2) The E. coli antibacterial test demonstrated that the sterilization rate of Ti-12Nb-1Ag was higher than that of the Ti-6Al-4V alloy and pure Ti. (3) The microstructural analysis revealed that Ti-12Nb-1Ag had an acicular martensite structure, with nano-Ag precipitates observed. Based on the results of the E. coli antibacterial test and the principles of sterilization of nano-precipitates and Ag, we inferred that the nano-Ag precipitates of Ti-12Nb-1Ag enhanced the antibacterial properties of the newly developed biomaterial, which is, namely, the Ti-12Nb-1Ag alloy.
