## Plasma based ion implantation Nitriding was performed on a medical grade CoCrMo alloy at 400 Β°C in N 2 or N 2 -H 2 atmosphere at a working pressure of 0.84 Pa for 2 h. Various surface treatment techniques were used to incorporate nitrogen into the CoCrMo alloy: without any plasma assistance, by
Diamond-like carbon films with different bias voltages were deposited on polished NiTi alloys by plasma immersion ion implantation and deposition (PIIID) using acetylene as precursor. The chemical structure of the DLC films was characterized by Raman scattering spectroscopy. The electrochemical beha
