Comparison of the Corrosion Behaviour of Differently Deposited PVD TIN/TiO2 Coatings on Electron Beam Modified Ti5A14V Alloy

摘要

In the particular study, the micropatterning of the Ti5A14V alloy in as-received, solution treated and solution and precipitated condition was done using electron beam surface modification (EBSM) by scanning electron beam. The nanostructured TiN/TiC>2 films were deposited over the EBSM Ti5A14V substrates using dc magnetron sputtering and cathodic arc and glow-discharge methods. The electrochemical potentiodynamic tests were performed in Ringer saline at 37±0.05 °C and a pH of 5.7 in order to determine the corrosion resistance behavior of the coated and uncoated EBSM substrates as compared with the bare as-received, solution treated and solution and precipitated samples. The presented results gave an idea of the corrosion behavior of the examined implant systems in aggressive environment and external conditions close to the body right.
