## Description

- description: In orthopedics, occasionally, different types of metals are used in
    applications in which they are in contact with each other. However, few studies
    have electrochemically investigated the galvanic corrosion of orthopedic implants
    formed of different metals. In this study, galvanic corrosion of Ti–6Al–4V ELI
    alloy, Co–Cr–Mo alloy, and 316L type stainless steel, which are used in orthopedics,
    and a newly developed Zr–1Mo alloy as a low-magnetic susceptibility material was
    evaluated in saline. Coupling of the Ti–6Al–4V ELI and Co–Cr–Mo alloys did not
    exhibit localized corrosion and maintained highly stable passive films. Coupling
    of the 316L type stainless steel and Co–Cr–Mo alloy, temporary localized corrosion
    occurred.  Similarly, coupling of the Zr–1Mo and Co–Cr–Mo alloys, temporary localized
    corrosion occurred. However, both of 316L type stainless steel and Zr–1Mo alloy
    were finally repassivated spontaneously with the immersion time. The degree of
    the localized corrosion of the Zr–1Mo alloy was smaller than that of 316L type
    stainless steel. No galvanic current was observed when the Ti–6Al–4V ELI and Co–Cr–Mo
    alloys were coupled. A slight galvanic current flowed when 316L type stainless
    steel or the Zr–1Mo alloy was coupled with the other alloys; however, the galvanic
    current with the Zr–1Mo alloy coupling recovered to zero after a certain period
    owing to repassivation. No metal ions were detected from the couplings with Zr–1Mo
    alloy.
