【 摘 要 】
TiAlN/Al2O3 multilayers with different Ar/N2 ratios were deposited on Sisubstrates in different N2 partial pressure by magnetron sputtering. The crystalline and multilayer structures of the multilayers were determined by a glancing angle X-ray diffractometer (XRD). A nanoindenter was used to evaluate the hardness, the elastic modulus and scratch scan of the multilayers. The chemical bonding was investigated by a X-ray Photoelectron Spectroscopy (XPS). The maximum hardness (36.3 GPa) and elastic modulus (466 GPa) of the multilayers was obtained when Ar/N2 ratio was 18:1. The TiAlN/Al2O3 multilayers were crystallized with orientation in the (111) and (311) crystallographic planes. The multilayers displayed stably plastic recovery in different Ar/N2 ratios. The scratch scan and post scan surface profiles of TiAlN/Al2O3 multilayers showed the highest critical fracture load (
