Abstract

A magnetized sheet plasma of several millimeters is used in the synthesis of titanium nitride (TiN). Sm-Co permanent magnets were placed below the Ti target to increase the sputtering yield. The Ti target is biased from –250V to –350V and is sputtered by Ar plasma produced at discharge current of 2.5– 4A and discharge potential of 60–90V. Steel substrates of dimensions 20x20x0.5 mm³ were prepared with N₂:Ar volumetric ratios of 1:3, 1:5 and 1:10. Ocular inspection of samples exhibit bright gold color associated with TiN. XRD characterization showed that all samples exhibit the (200) and (311) peaks of TiN and the non-stoichiometric Ti₂N (220) facet. Deposition rate of TiN increased to ~0.35μm/min as shown in the cross-sectional SEM results. This doubles what was previously obtained. Scanning electron micrograph results give a comparative morphological picture of the samples. Vickers hardness results gave the largest hardness value of 20.094GPa.
