Abstract

Nanocrystalline MoN coatings were prepared by inductively coupled plasma magnetron sputtering (ICPMS) changing the plasma power from 0 W to 200 W. The properties of the coatings were analyzed by x-ray diffraction, field emission scanning electron microscopy, atomic force microscopy, nanoindentation tester and semiconductor characterization system. As the ICP power increases, the crystal structure of the MoN coatings changed from a mixed phase of Υ-Mo2N and α-Mo to a single phase Υ-Mo2N. MoN coatings deposited by ICPMS at 200 W showed the most compact microstructure with the highest nanoindentation hardness of 27.1 GPa. The electrical resistivity of the coatings decreased from 691.6 μΩ cm to 325.9 μΩ cm as the ICP power increased.
