摘要：
AlxOy films by DC reactive magnetron sputtering were annealed in air ambient at 500 degrees C for 1 h with different heating rates of 5, 15, and 25 degrees C/min. Then heat treatments at 900 degrees C were carried out on these 500 degrees C-annealed films to simulate the high-temperature application environment. Effects of the annealing heating rate on structure and properties of both 500 degrees C-annealed and 900 degrees C-heated films were investigated systematically. It was found that distinct gamma-Al2O3 crystallization was observed in the 900 degrees C-heated films only when the annealing heating rates are 15 and 25 degrees C/min. The 500 degrees C-annealed film possessed the most compact surface morphology in the case of 25 degrees C/min. The highest microhardness of both 500 degrees C-annealed and 900 degrees C-heated films were obtained when the annealing heating rate was 15 degrees C/min.
