Feng et al. [168] used ion implantation
technique for coating a thin layer silver on SS 316L. The
potentiostatic tests revealed a significant decrease in ICorr from 10
to 0.7 mAcm2 after Ag implantation. In addition, the test showed
that ICR value improved from 312 to 78mUcm2. The results showed
that the overall reduction in ICR by ion implantation depends on
the value of precipitated silver nanoparticles in the implanted layer,
the passive layer thickness, and amounts of metallic phase of silver
and nickel. In addition, the coating method, coating process conditions
(especially temperature), surface pretreatment, and the
coating thickness can obviously affect the coating quality, thereby
ICR value.
