Synthesis and characterization of zirconium nitride coatings by cathodic arc sputtering technique

M. N. Sarwar, M. S. Awan and S. Akbar

Abstract

Polycrystalline zirconium nitride films (560 nm) were deposited on stainless steel (SS-316) substrates using the multi-target cathodic arc sputtering technique. Deposition was carried out under N2 reactive atmosphere (4 × 10−3 mbar) at two different temperatures, 150 and 200 °C. X-ray diffraction studies show that reflections from planes changed from (111) to (200) for deposition temperatures of 150 °C and 200 °C, respectively. Films deposited at 150 °C and 200 °C bear a critical load of 6.4 N and 6.8 N respectively, showing better adherence at higher temperature. This may be the result of film–substrate diffusion at the interface.
