The fine rnicrostrueture of the Y-modified ion plated Ti(Y)N coating/substrate steel A3 system has been examined by means of TEM and microdiffraction technique.It was revealed that the interface consists of 3 sublayers,i.e.α-Fe+Y_6Fe_(23),Ti+Y+FeTi and Ti_2N+YN +Ti_xN_y.The thicknesses of them are about 200,50 and 120 nm respectively.The phases in the transition area seem to have certain orientation relations.The mechanism of interface formation has also been discussed.

采用透射电子显微镜及微衍射技术,研究了稀土钇改性的离子镀Ti(Y)N膜与A3钢基材之间的界面精细结构。结果表明:Ti(Y)N/A3系统界面是由三个亚层构成,由于Y的添加导致了界面三个亚层中形成了Y_6Fe_(23),Y和YN相,其中Y_6Fe_(23)和Y与α-Fe,FeTi及Ti_2N相之间存在一定的位向关系。本文还讨论了该界面形成机理。
