The objective of the present work is to investigate the effect of DC power variation on structural, wettability and tribological properties of TANTALUM NITRIDE (cas 12033-62-4) coatings deposited by DC reactive magnetron sputtering. The X-ray diffraction graphs of tantalum nitride coating show evolution of various textures of tantalum nitride with an increase in DC power. Wettability test showed promising results for hydrophobicity as the DC power supply was increased from 230 to 430W. The lowest contact angle of 95.6° was achieved at DC power of 230W and the highest contact angle of 100.2° was achieved at 430W. The wear test was done on uncoated and tantalum nitride coated cylindrical pins of brass and mild steel. The pins showed improvement in wear resistance when coated with tantalum nitride.
