Abstract Titanium nitride (TiN) coatings were deposited onmild steel (MS) by direct current reactivemagnetron sputtering. With the aim of improving the corrosion resistance of TiN, an additional nickel interlayer was brush plated on the steel substrates before TiN film formation. The phases have been identified with X-ray diffraction analysis. The hardness values of TiN layers were found to increase with the increase in thickness of the Ni interlayer. The wear track investigations of TiN layers showed that the TiN MS system was worn out by abrasive wear mechanism while on the film with Ni interlayer is by adhesive wear. It was found that the TiN Ni MS stack had a weaker tendency towards corrosion and higher corrosion resistance in 3?5%NaCl than the bare MS substrate, Ni MS and TiN MS specimen.
