查询词典 brazing seam

The results show that heating at1500oC for 10 minutes in vacuum is the best brazing process. In the ceramic side none defects was observed at the interface of ceramic and solder, which leads to uniform brazing seam and excellent airtightness.

本文对单晶Al2O3/Pd/Nb焊接工艺、界面组织结构等进行了研究分析，结果表明在真空状态下，温度为1500℃，保温10分钟得到的焊缝均匀一致，没有任何的孔洞缺陷，气密性检测说明焊接情况良好。

Methods: The brazings of the best brazing properties were selected by means of moistness test, filling seam test, mechanical property test and micro structural analysis.

对1＃ ～5＃5种钎料进行了润湿性试验、填缝试验、力学性能测试及显微组织分析。

The brazing seam mass is therefore good and bad the mass being related to a weldment is good and bad , mass that can affect to weldment sigmatism function , how to raise therefore, we answer a brazing seam carries out the analysis studying.

因此焊缝的质量好坏关系到焊件的质量好坏、会影响到焊件的使用性能，所以，我们应对如何提高焊缝的质量进行研究分析。

Compared with the joint brazed with Cu-Ti filler metal, the content of Cu in the reaction layer adjacent to the stainless steel is higher than the joint brazed with Cu-Co-Ti filler metal, so is the content of Nb in brazing seam.

与Cu-Ti钎料接头相比，Cu-Co-Ti钎料接头中钎缝与不锈钢侧的反应层中Cu含量较高，钎缝中Nb含量也较高。

As the brazing temperature was low or the holding time was short, lots of low-melting M3B2 were precipitated in the central part of the brazing seam.

当钎焊温度较低或保温时间较短时，钎缝中央生成大量的M3B2；随着钎焊温度的升高及保温时间的延长，钎缝中M3B2、MC减少，M23C6增多、长大。
