Titanium Nitride (TiN) was deposited on aluminium alloy Al6061 using reactive DC magnetron sputtering technique. X-Ray diffraction and EDAX confirmed the presence of TiN phase in the coating. Optical microscopy showed the golden bronze coloured TiN coating at a N2/Ar ratio of 0.47. Maximum composite Microhardness hardness of 2210 (HK) was obtained at 5g load for the coating deposited at a ratio (N2/Ar) of 0.60. The dry sliding wear behaviour was studied by pin-on-disc machine. Oxidation wear prevailed during the sliding test. Coatings deposited at a ratio (N2/Ar) of 0.47 and 0.60 showed better wear resistance as compared to uncoated specimens.
