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 metallizing layer was reaction with Al2O3 grains on the surface of ceramic. The latter was that glassy phase in metallizing layer migrated to ceramics, and glassy phase in ceramics migrated to metallizing layer.关键词
