摘要:
Ti-Al-N thin films were synthesized utilizing a high power impulse magnetron sputtering (HIPIMS) from a Ti2AlN compound target. The deposition temperatures and bias voltages were varied in the range of room temperature (RI) to 450 degrees C and 0 V to -70 V. respectively. It was indicated that amorphous films formed at low deposition temperatures of RT and 300 degrees C, which changed into MAX-phase Ti2AlN films after vacuum annealing at 800 degrees C for 1 h. Densely packed nano-fibrous crystalline films mainly composing of Ti2AlN MAX phase and tetragonal Ti2N phase were acquired at deposition temperature of 450 degrees C, which exhibited stable film structure during vacuum annealing at 800 degrees C. The Ti2AlN-Ti2N composite films exhibited excellent oxidation and corrosion resistance, as compared to (Ti,Al)N film having same Ti/Al ratio and/or TiN film synthesized by a hybrid coating system with HIPIMS and DC pulse magnetron sputtering. The mechanical properties of the Ti2AlN-Ti2N films were also investigated in this work. (C) 2012 Elsevier B.V. All rights reserved.
