Abstract

The mechanical properties and morphology of the surface of titanium nitride films deposited by reactive sputtering with a hot target have been investigated. It was founded that films synthesized at low nitrogen flow rate and at high discharge current density have the highest hardness (up to 30 GPa) and Young’s modulus (up to 300 GPa). The analysis of films surface images obtained by atomic force microscopy is carried out. The typical grain size and its shape were determined. Films with the greatest hardness have the largest grains.
