| 摘 要： | 用Mo-Mn-Ti-Si-Al系统膏剂金属化两种氧化铝陶瓷材料。封接强度实验结果表明,Mo-Mn-Ti-Si-Al系统膏剂不适宜高纯Al2O3陶瓷的金属化封接,而比较适宜95%Al2O3陶瓷的金属化封接。用该膏剂金属化95%Al2O3陶瓷,其焊接强度最高值可达150MPa以上。通过显微结构分析发现,高纯Al2O3陶瓷的金属化机理与95%Al2O3陶瓷金属化的机理不同,前者中玻璃相仅仅通过高温熔解-沉析与表面的Al2O3晶粒反应,后者金属化层内玻璃相与陶瓷内玻璃相相互迁移渗透。

| Abstract: | Two kind of alumina ceramics were metallized by Mo-Mn-Ti-Si-Al system paint.The results of sealing strength indicated that Mo-Mn-Ti-Si-Al system paint was fit for 95% Al2O3 ceramic,but it was not fit for high pure alumina ceramics.And strength of metal-95% Al2O3 ceramic seals reached above 150MPa.By analyzing the microstructure of metal-alumina ceramics seal section,the metallizing mechanism of high pure alumina ceramics was different from that of 95% Al2O3 ceramic.The former was that glassy phase in metall... |
