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.
