中文摘要:

以铜锌金焊接的 Au-Pd-Co-Ni-V 合金为 AlN 被设计陶器的加入。它 AlN 上的 wettability 与无柄的落下方法被学习。结果证明接触角度与增加温度并且延长保持时间逐渐地被减少。健全 AlN/AlN 关节为 10min 在 1170 °C 与以铜锌金焊接的合金被完成。AlN/AlN 关节的微观结构被扫描电子显微镜学(SEM ) 检验。元素 V 在界面的反应在之间起了活跃作用,这被发现陶器并且以铜锌金焊接的合金。V 反应了, N 从 AlN 分解了,导致了 V-N 化合物的形成。基于精力散的光谱学(版本) 和 X 光检查衍射(XRD ) 分析结果, V-N 反应产品作为 V 2 N。全面反应能被下列方程在以铜锌金焊接的过程期间描述:2V+AlN+2Pd=V 2 N+Pd 2 艾尔。AlN/AlN 关节以铜锌金焊接, Au-Pd-Co-Ni-V 以铜锌金焊接合金在房间温度展出了 162.7MPa 的三点的拐弯力量,并且在拐弯测试下面,关节的破裂发生在 AlN 陶器的底层。

英文摘要:

An Au-Pd-Co-Ni-V brazing alloy was designed for AIN ceramic joining. Its wettability on AIN was studied with the sessile drop method. The results showed that the contact angle was decreased gradu- ally with increasing temperature and the prolonging of holding time. Sound AIN/AIN joints were achieved with the brazing alloy at 1170 ℃ for 10 min. The microstructure of the AIN/AIN joints was examined by scanning electron microscopy (SEM). It was found that element V played the active role in the interfacial reaction between the ceramic and the brazing alloy, V reacted with N decomposed from AIN, resulted in the formation of V-N compound. Based on the energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD) analysis results, the V-N reaction product was verified as V2N. The overall reaction during the brazing process can be described by the following equation: 2V + AIN + 2Pd = V2N + Pd2AI. The AIN/AIN joints brazed with the Au-Pd-Co-Ni-V brazing alloy exhibited three-point bend strength of 162.7 MPa at room temperature, and under the bend test the fracture of the joint occurred at the AIN ceramic substrate.
