Characterization of TiAlBN Nanocomposite Coating deposited via Radio Frequency Magnetron Sputtering using Single Hot-Pressed Target

摘要

TiAlBN coatings have been deposited at varying bias voltage of 0, -60, and -150 V by radio frequency (RF) magnetron sputtering technique. A single hot-pressed Ti-Al-BN target was used for the deposition process. With glancing angle X-ray diffraction analysis (GAXRD), the nanocrystalline (nc-) (Ti,Al)N phase was identified. In addition, the existence of BN and TiB_2 amorphous (a-) phase were detected by X-ray photoelectron spectroscopy (XPS) analysis. Thus, the deposited TiAlBN coatings were confirmed as nc-(Ti,Al)N/a-BN/a-TiB_2 nanocomposite. On the other hand, it was found that optimum bias voltage used in present study is -60 V where the deposited TiAlBN coating exhibits an excellent adhesion quality. The adhesion quality of the coatings deposited at -60 V bias voltage is classified as HF 1 evaluated using the Rockwell-C adhesion test method (developed by the Union of German Engineers).
