Effects of the High-Temperature Plasma Immersion Ion-Implantation Treatment on Corrosion Behavior of Ti-6Al-4V

Improvements of the surface properties of Ti6Al4V by plasma based ion implantation at high temperatures

“…Meanwhile, the samples treated during 1 h showed implanted layers with 25 nm of thickness. Compared to the previous results of PBII at high temperature (up to 800°C) in the same alloy [18], the depth profiles obtained for samples treated at 760°C and 800°C were very similar. The small difference in the treatment temperature (40°C) did not have a great influence in the thickness of the N-rich layer.…”

“…In the nitrogen PBII treatments at 800°C [Refs. 17,18] and in the treatments of this work, the polarization curves analysis indicated that the corrosion rate is very similar for all the treated samples at high temperature, i.e., the corrosion current density values are very similar. For all treatments at temperatures between 660°C and 800°C, the corrosion potential was below the corrosion potential of the untreated sample.…”

“…da Silva et al in Ref. [18]. The Ti6Al4V surfaces submitted to corrosion tests exhibited less intense attacks after nitrogen implantation at high temperatures than before these treatments.…”

Enhanced Mechanical and Tribological Properties of AISI 304 Stainless Steel by Using a Hybrid Nitriding Process

“…Tribological analysis was carried out in a ball‐on‐disk CSM tribometer, where the profile of the channel obtained was examined in an Alpha‐Step 500 profilometer. Corrosion resistance measurements were carried out by the electrochemical method 9. The potentiodynamic polarization curves were obtained by means of an EG&G PAR 283 potenciostat, using a conventional three‐electrode glass cell.…”
