Abstract
TiN PVD coating and plasma nitriding are two well-known techniques for improving tribological properties of treated samples. The study examines the corrosion resistance of plasma nitrided and TiN coated Ti-6A1-4V samples. The potentiodynamic polarization technique was used to measure the corrosion rate and corrosion resistance of the substrates. A micro PIXE technique was employed to determine the nitrided zone depth profile. SEM was carried out to investigate the pitting defects. To achieve a comparative study, TiN coated, nitrided and untreated samples were examined. It was found that TiN coating improves the corrosion properties, but nitriding worsens the corrosion resistance of the substrate.
