“…Hydrogen also decreased the elongation of Ti 50 Ni 30 Cu 20 alloy (referred as “hydrogen embrittlement”). It was reported that hydrogen accelerated the crack initiation and propagation (Yoshida et al, 2012). The role of hydrides on the hydrogen embrittlement behavior of Ni-Ti alloy has been discussed by several authors.…”

The B19-phase transition and the related tensile properties of Ti50Ni30Cu20 shape memory alloys were investigated after hydrogen doping. The results revealed that the presence of hydrogen suppressed the B2–B19 transition by decreasing transformation enthalpies. Aging at room temperature lowered martensitic transformation temperature, which might have been associated with the variation of hydrogen contents and states. Ti50Ni30Cu20 shape memory alloys manifested high thermal cycling stability after the aging treatment. In addition, the increase in the hydrogen content was accompanied by an increment in detwinning stress of B19 phase, whereas the elongation of Ti50Ni30Cu20 alloys decreased. Based on our analysis, these effects were caused by the combined activities of different hydrogen states, including those of hydrides and solid-solution hydrogen.

“…that increasing it by heat treating the NiTi alloy (processed by LENS) makes it more susceptible to corrosion [49]. There are also studies that did not observe any modification on the localized corrosion resistance of cast or wrought NiTi with the martensitic phase [56,57]. These differences may come from the various cooling rates applied, which may influence the final hardness, and from the powder consolidation method employed, which can impact corrosion resistance.…”

The purpose of the present study was to experimentally assess the synergistic effects of wear and corrosion on NiTi alloy in comparison with Ti-6Al-4V alloy, the most extensively used titanium alloy in biomedical applications. Both alloys were processed by an additive manufacturing laser beam directed energy deposition (LB-DED) technique, namely laser engineered net shaping (LENS), and analyzed via tribocorrosion tests by using the ball-on-plate configuration. The tests were carried out in phosphate buffered saline solution at 37 °C under open circuit potential (OCP) to simulate the body environment and temperature. The synergistic effect of wear and corrosion was found to result in an improved wear resistance in both materials. It was also observed that, for the process parameters used, the LB-DED NiTi alloy exhibits a lower tendency to corrosion as compared to the LB-DED Ti-6Al-4V alloy. It is expected that, during the service life as an implant, the NiTi alloy is less susceptible to the metallic ions release when compared with the Ti-6Al-4V alloy.
