Thin nanocrystalline Titanium nitride (TiN) films were deposited on mild steel (MS) substrates using reactive direct current magnetron sputtering. With the aim of improving the corrosion resistance an additional Nickel interlayer of about 5 mu m thick was brush plated on to the steel substrates. X-ray diffraction analysis showed the polycrystalline nature of the sputtered TiN films. SEM analysis showed uniform surface morphology with dense columnar structure. Laser Raman spectroscopy revealed the presence of characteristic peaks of TiN at 320, 440 and 570 cm(-1). The optical quality of the film was confirmed from the photoluminescence (PL) spectrum recorded at room temperature. The corrosion behavior of the coatings in 3.5% NaCl solution was studied using electrochemical techniques.
