TiBCN coatings were prepared by magnetron sputtering installed with two kinds of target materials (Ti and TiB2) in a mixed Ar, N2 and C2H2 ambient. The results showed that the TiBCN coatings could be successfully obtained by reactive sputtering with Ti and TiB2 dual targets. Raman spectroscopy indicated that TiBCN had similar spectra with DLC, which confirmed with high C content, in the wave range of 1000 ~ 2000 cm-1. The hardness of the coatings would decrease with an increase of N and the sp3 bond in the coatings. The friction coefficient against soda-lime glass ball was decreased from 1.3 of blank WC-Co substrate to 0.35 of the coatings in dry sliding condition.

This study aims to investigate the effects of nitrogen flow rate (0–2.5 sccm) on the structure and properties of TiZrN films. Nanocrystalline TiZrN thin films were deposited on Si (001) substrates by unbalanced magnetron sputtering. The major effects of the nitrogen flow rate were on the phase, texture, N/(Ti + Zr) ratio, thickness, hardness, residual stress, and resistivity of the TiZrN films. The nitrogen content played an important role in the phase transition. With increasing nitrogen flow rate, the phase changed from mixed TiZr and TiZrN phases to a single TiZrN phase. The X-ray diffraction results indicated that (111) was the preferred orientation for all TiZrN specimens. The N/(Ti + Zr) ratio of the TiZrN films first increased with increasing nitrogen flow rate and then stabilized when the flow rate further increased. When the nitrogen flow rate increased from 0.4 to 1.0 sccm, the hardness and residual stress of the TiZrN thin film increased, whereas the electrical resistivity decreased. None of the properties of the TiZrN thin films changed with nitrogen flow rate above 1.0 sccm because the films contained a stable single phase (TiZrN). At high nitrogen flow rates (1.0–2.5 sccm), the average hardness and resistivity of the TiZrN thin films were approximately 36 GPa and 36.5 μΩ·cm, respectively.
