| 摘 要： | 铬酸镧陶瓷脆性高、难以变形,使其在加工上存在难度。利用陶瓷连接技术可以将小部件连接为大部件,实现低成本制造形状复杂的大型陶瓷构件。以铬酸镧的前驱体料浆作为中间层材料,利用放电等离子技术进行了铬酸镧陶瓷的连接,测定了连接件的连接强度,并借助SEM、EDS等手段分析了连接温度及保温时间对连接件强度的影响。结果表明,连接温度为1400℃时,连接件可以获得最高的连接强度,连接过程中母材中出现第二相Cr4O5。

| Abstract: | Lanthanum chromate ceramics with poor tensile properties, high brittleness, difficult deformation and high hardness is difficult to process. Large ceramic components with complex shapes can be fabricated at low cost by ceramic joining technology. In this paper, the lanthanum chromate precursor slurry was used as the interlayer material, and the lanthanum chromate ceramic was joined by spark plasma technology. And then the bonding strength of the joining was measured. The influence of joining temperature and holding time on the strength of the joint was analyzed by means of SEM, EDS and so on. |
