Arc Deposition

Monolayered TiSiN and multilayered TiSiN/CrN coatings were synthesized by a cathodic arc deposition process. The chromium and Ti/Si (80/20 at.%) alloy targets were adopted as the cathode materials, altering the ratio of cathode current (I[TiSi]/I[Cr]) to obtain various multilayer periodic thicknesses of multilayered TiSiN/CrN coatings. X-ray diffraction and TEM analyses showed that all the deposited monolayered TiSiN and multilayered TiSiN/CrN films possessed the B1-NaCl structure. In this study, it was shown that the multilayer periods (Λ) of the TiSiN/CrN deposited at I[TiSi]/I[Cr] cathode current ratios of 1.8, 1.0, and 0.55 were 8.3 nm, 6.2 nm, and 4.2 nm, respectively, with multilayer periodic thicknesses decreasing with smaller I[TiSi]/I[Cr] cathode current ratios. An amorphous phase was found at the boundaries of the TiN/CrN column grains. In addition, the multilayered TiSiN/CrN coatings displayed a lamellar structure that was well-defined and nonplanar between each TiN and CrN layer.

Poor Adhesion

Four hard thin coatings (TiSiN, TiN-CrN multi, AlTiN a WC) were deposited on the WC+Co substrate by cathodic arc deposition. Adhesion test of PVD coatings was evaluated by comparison failure of coating surfaces. The surface features after the Rockwell indentation test were examined by light microscopy. The results showed that the AlTiN and WC coatings exhibited acceptable failure and are appropriate for usage in practice. Unlike them, had TiSiN and TiN-CrN coatings poor adhesion, which resulted in unacceptable failure after Rockwell C test.
