Abstract
|
In this study, TiN coatings were deposited on Ti-6Al-4V alloy surface using cathodic arc evaporation (CAE) deposition process at three different bias voltages (-150, -200 and -250 V) applied to the substrate. In this regard, the effect of bias voltage on the microstructure and corrosion behaviour of coatings was studied. The microstructure of the coated specimens was analysed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM).
