采用电子束蒸发的方法在抛光的200℃AlN陶瓷衬底上淀积厚度为200nm的Ti膜,并在高真空中退火.利用二次离子质谱(SIMS)、卢瑟福背散射谱(RBS)、俄歇电子能谱(AES)和X射线衍射分析(XRD)技术,研究了从200~850℃温区内Ti与AlN的固相界面反应,给出了界面组分分布随退火温度和时间的变化关系.在界面区发现了三元铝化物并观测到铝化物产生与发展过程.指出铝化物由Ti-Al二元和Ti-Al-N三元化合物组成.最后利用热力学理论对实验结果进行了解释
A Ti film having a thickness of 200 nm was deposited on a polished 200 ° C AlN ceramic substrate by electron beam evaporation and annealed in a high vacuum. The effects of Ti and AlN in the temperature range of 200 ~ 850 ℃ were studied by using SIMS, RBS, AES and XRD. The relationship between the distribution of interface components and the annealing temperature and time is given. Ternary aluminides were found in the interface zone and the production and development of aluminides were observed. It is pointed out that the aluminides consist of Ti-Al binary and Ti-Al-N ternary compounds. Finally, the thermodynamic theory is used to explain the experimental results
