中文摘要:
      本文主要研究了55% SiCp/Al复合材料与PbO-ZnO-B2O3玻璃封接过程中的润湿性和界面结合机理。研究结果显示:随温度升高,玻璃在四种母材上的铺展面积逐渐变大,润湿角减小,润湿能力提高,Al2O3陶瓷和SiC陶瓷与玻璃封接的铺展面积较大,润湿角较小,润湿性要优于复合材料。在450 ℃~490 ℃范围内将玻璃与55% SiCp/6061Al进行封接时,当封接温度高于470 ℃,在封接界面出现气泡,且随着温度升高气泡数量增多,尺寸变大;在460 ℃下封接时,玻璃与55% SiC/Al复合材料封接界面存在约为12 μm的元素互渗区域,490 ℃时玻璃与Al2O3陶瓷的界面分界线清晰,与SiC陶瓷封接界面处,偏向玻璃侧存在SiC颗粒的渗入。

英文摘要:
      The wettability and interface bonding mechanism between 55% SiCp/Al composite materials and PbO-ZnO-B2O3 glass during the sealing process were investigated in this article. The results showed that the glass would spread wider with the increase of temperatures. That is to say the wettability angle became smaller and the wettability was improved. The spreading area of glass on Al2O3 and SiC were larger and the wettability angles were smaller than those on the composites. The sealing temperature between glasses and 55% SiCp/6061Al range from 450~490 ℃. When the sealing temperature is higher than 470 ℃, bubbles would appear in the sealing interface and the number of bubbles increased with the increasing of temperatures, at the same time the size of the bubbles would became larger too. When the sealing temperature is 460 ℃, a 12 μm diffusion region appeared between the glass and 55% SiC/Al composites. When the sealing temperature is 490 ℃, there was a clear boundary between the glass and Al2O3 ceramic, and the SiC particles would diffuse into the glass when the glass and SiC ceramic were sealed together.
