摘要
通过X射线衍射分析和扫描电镜观察研究了利用融盐热歧化反应法在氮化铝陶瓷表面生成的钛金属化复合膜的组成、金属化膜与氮化铝陶瓷基体之间的界面反应及界面层的显微结构。研究发现,钛金属化膜非常均匀致密,膜层与氮化铝陶瓷基体结合紧密,形成了一扩散层,钛与铝组元浓度在该扩散层中呈梯度分布,沉积到AlN陶瓷表面的钛金属与AlN发生反应主要生成TiN0.3、TiAl3和Ti9Al23。
The mechanism of interfacial reaction between AlN and Ti deposited by disproportional reaction method has been determined. The composition of the coating layers and the microstructure of the reaction products were investigated by XRD and SEM. The result show that the metallized film was consisting of TiN0.3, TiAl3 and Ti9Al23. The metallized film is homogenous and firmly bound onto the AIN ceramics surface.
