摘 要: 将Ti Al粉末冶金靶用多弧离子镀技术制备了TiAlN/Ti涂层。用XTEM等手段研究了涂层的界面结构。研究表明,TiAlN及Ti层均呈柱状多晶组织,在Ti过渡层与高速钢基底之间存在界面相FeTi,它与基底中的α Fe相具有一定的取向关系。 TiAlN/Ti coating was deposited by multiarc ion plating (MAIP) method with hotpresssintered TiAl alloy used as the target. The interface structure of coating was studied with XTEM. The results show that both TiAlN layer and Ti layer have polycrystalline columnar structure, an interface phase FeTi, which exists between the Ti transition layer and the high speed steel (HSS) substrate has certain orientation relationship with the αFe phase in the substrate.
