摘要：
A dense and well-adhered diamond-like carbon (DLC) coating was prepared on the nickel-titanium (NiTi) alloys by plasma immersion ion implantation and deposition (PIIID). Potentiodynamic polarization tests indicated the corrosion resistance of the NiTi alloys was markedly improved by the DLC coating. The Ni ions release of the NiTi alloys was effectively blocked by the DLC coating.
