摘　　要：成功制备了多弧离子镀 Ti Al N/Ti多元复合涂层的截面透射试样 ,并分别用 TEM和 EDS等手段研究了涂层的组织结构和界面结构。结果表明 ,多晶 (Ti,Al) N相是 Ti Al N的主要组成相 ,过渡 Ti层呈现多晶 α- Ti结构。研究发现 ,在 Ti Al N- Ti过渡层界面、Ti过渡层 - HSS基体界面分别存在一个薄的中间层 ,通过衍射和 EDS分析认为前者是 Ti2 Al N相 ,而后者则是 Fe Ti界面相 ,用 XTEM还观察到 Fe Ti相与基体The cross-section transmitting sample of TiAlN/Ti multicomponent composite coating was prepared by multi-arc ion-plating.The structures and interfaces of the coating was analyzed by TEM and EDS.The results show that (Ti,Al)N multicrystal phase is the main composition of TiAlN layer and the transitional Ti layer shows itself multicrystal α-Ti structure.The results also show that thin intermediate layers exist in TiAlN transitional layer interface and Ti transitional layer-HSS substrate interface,respectively,by means of diffraction and EDS,the former is considered as Ti 2AlN phase and the latter is considered as FeTi interface phase.The orientation relationship between FeTi phase and M' matrix phase has been examined by XTEM,too.
