Structure and properties of hard and superhard Zr-Cu-N nanocomposite coatings

Original language description

Zr-Cu-N nanocomposite films represent a new material of the type-nanocrystalline transition metal nitride (nc-MeN)/metal. In the present work, films were deposited onto steel substrates using unbalanced dc reactive magnetron sputtering of a Zr-Cu (62/38at.%) target. Film structure, chemical composition, mechanical and optical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, wavelengthdispersive electron probe microanalysis, depth-sensing microindentation and spectroscopic ellipsometry. It was found that (i) there is a strong correlation between the film structure, Cu content and film properties and (ii) either hard or superhard Zr-Cu-N films can be formed. The superhard coatings with hardness H > 40 GPa are characterized by a columnar structure, a strong 111 XRD peak from ZrN grains and no diffraction peaks from Cu.
