Aimed to the testing problem of brazing quality of arc surface electric contact, its ultrasonic C-scan image model was built firstly.

针对弧形触点的钎焊质量检测问题，首先建立了弧形触点的超声c扫描图像模型。

Ion implantation can surely improve the joining ability of the ceramic surface, but the reasons of improving the brazing ability other than the electric conductivity should be found.

离子注入确实可以显著提高陶瓷材料的可焊性，但提高陶瓷材料表面导电性并不是提高其钎焊性能的主要因素。
