    摘要:

    鉻酸鑭陶瓷拉伸性能差,脆性高、難以變形、硬度高使得加工上存在難度,陶瓷連接技術(shù)可以實現(xiàn)低成本制造形狀復雜的大型陶瓷構(gòu)件。本文采用鉻酸鑭前驅(qū)體料漿作為中間層材料,利用放電等離子技術(shù)進行了鉻酸鑭陶瓷的連接,測定了連接件的連接強度,并借助SEM、EDS等手段分析了連接溫度及保溫時間對連接件強度的影響。

    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.
