Abstract

The nano-crystalline films of zirconium nitride have been synthesized on implants for trauma surgery made of AISI 316 L stainles steel by using vacuum-arc deposition under RF-biasing mode in “Bulat” type device. Structure examinations – X-ray diffraction analysis (XRD), X-ray fluoriscent analysis (XRF), scanning electron microscopy (SEM) with microanalysis (EDX), nanoidentation method – were performed to study phase and chemical composition, surface morphology, microstructure and nanohardness of ZrN coatings. The corrosion resistance of coatings has been tested in 0.9 % quasiphysiological NaCl solution.
