Abstract
This project involves the deposition of superhard nanocomposite coatings of TiN/Si3N4 using unbalanced magnetron sputtering system equipped with ion beam assisted facility. Unbalanced magnetron sputtering combined with pulsed dc power supply is a powerful tool for the deposition of compound thin films. The coatings were deposited on silicon substrates under high vacuum conditions. TiN/Si3N4 films were deposited at different silicon concentrations and bias voltages. X-ray diffraction results confirmed the nanocrystalline nature of the coatings. NHT measurements showed that the nanocomposite coating had high hardness values. The surface morphology of the TiN/Si3N4 coating was studied using AFM.
