表面涂层

In our experiments, the hafnium films were deposited on molybdenum substrates by radio frequency magnetron sputtering technology, and the barium oxide layers were prepared by the chemical method to simulate the grid structure of traveling wave tubes. Then, the surface phase and compositional change in the grid was studied under high temperature by annealing from 900K to BOOK, which can be used in explaining the suppression mechanism of hafnium film.

实验中，利用射频磁控溅射技术在Mo基底上制备了Hf膜，并利用化学方法制备了BaO涂层以模拟行波管栅极结构，随后在N_2保护下，通过在900K到1300K范围内退火，研究栅极处于高温工作环境下表面相结构和成分的变化，以此解释了Hf薄膜抑制栅极电子发射的工作机理。

Thermal barrier coatings consist of an electron-beam physical-vapor deposited NiCoCrAlY bond coat and 7 wt.% yttria partially stabilized zirconia top coat with a tetragonal phase. The YPSZ top coat shows a columnar grains forming dense clusters with gaps among grain clusters. The roughness of the as-deposited ceramic top coat is relatively low, but some spots of prominent growth defects can be observed. Such defect is a bundle of zirconia columns.

采用EB-PVD方法沉积热障涂层，其粘结层为NiCoCrAlY，陶瓷层为7wt%Y_2O_3部分稳定的ZrO_2，其表层为单一的四方ZrO_2相，其表层比较致密，但有一定的粗糙度，表面存在一些凸出来的斑点状ZrO_2柱状晶，柱状晶粒簇拥成团，团簇间存在间隙。
