Table 2
Corrosion behavior of the dissimilar interface in a 3.56 wt.% NaCl solution.
| Sample history | mV (SCE) | Corrosion rate (mm/year) |
| Ti-6Al-4V | 1300 | 1.07 × 10−3 | Interface of cobalt clad on titanium without copper interlayer | 437 | 2.43 ×10−3 | Interface of cobalt clad on titanium with a 30 mm copper interlayer | 700 | 1.26 × 10−3 |
