“…Metal ions can be released due to friction between the joints. The released Ni has been shown to be directly incorporated into the living cells, changing their functions [36]. The cell activity is inversely related to released Ni content, where a significantly higher cell number can exist over the protected NiTi with lower Ni release [35].…”

“…Simply put, the more the coating is corrosion resistant, the lower Ni is leached out [37]. It is possible to minimize the concentration of the released Ni by controlling the operating parameters and increasing the number of the deposited layers [36,38,39]. As a novel strategy, the surface of NiTi can be modified by heat treatment under a He and H2 atmosphere.…”

This article was prepared from a project assigned in a graduate class, BME 7371, Failure Assessment of Medical Devices, taught at Wright State University by the senior author. The device was donated for the study which was successfully retrieved after 93 days in-vivo. Even-though the mechanical integrity of the device held in-tact, the microscopic observations revealed that the damage via corrosion and scratching took place on the surface of the device. The image reconstructed in 3D using image-J software to determine device roughness and depth-of-pits. Results presented in this paper show that damage starts developing in these devices after the implantation that resulted in premature failure in many cases as reported in the media and literature.

“…However, the material failures caused by surface corrosion are inevitable. Therefore, enhancing surface property is the basis for the long-term use of additive manufacturing of NiTi [11][12][13][14]. Surface treatment is a commonly used method to improve surface corrosion resistance, such as laser cladding [15] and surface film [16].…”

“…As we all known, SLM in additive manufacturing technology is widely used in the processing of NiTi alloys [26][27][28]. However, there are still a series of questions on the surface of SLM-NiTi, such as the release of Ni 2+ [12,29], and the corrosion behavior [30] relatively need to be improved. Therefore, it is feasible and necessary to improve the corrosion resistance of NiTi alloy surface by femtosecond laser surface treatment.…”

NiTi alloys are commonly used in many fields such as aerospace, mechanical engineering due to their excellent mechanical properties and shape memory effect. In recent years, the emergence of selective laser melting (SLM) technology provides a new method for the preparation of NiTi parts. But the surface corrosion failure of SLM-NiTi is the most common problem. This paper mainly focuses on the research of femtosecond laser shock peening of the surface of SLM-NiTi alloy to improve the corrosion resistance. Selecting different scanning space (1 μm, 3 μm, 5 μm, 10 μm), and analyze the surface morphology of the material through the OM, SEM, EDS and white light interferometer, and investigate the surface nanohardness and corrosion resistance through nanoindentation and electrochemical testing. The research results show that part of the TiO2 is formed under different scanning spaces, and part of NiO is formed when the scanning space is 1μm. At the same time, it is found that the sample under the condition of 10 μm has the most excellent corrosion resistance and nanohardness. The nanohardness reaches 1303 ± 40 HV and the corrosion current density reaches 1.45 ± 0.1 × 10−9 A·cm−2. Proper femtosecond laser treatment can effectively improve the surface strength and corrosion resistance of the NiTi alloys.
