Method for permeation connection of zirconia ceramics through glass solder
The invention discloses a method for permeation connection of zirconia ceramics through glass solder, and belongs to the technical field of welding. The method comprises the steps: grinding and polishing the surfaces of two to-be-welded zirconia ceramics to be smooth; preparing glass solder powder according to a route of ball milling, drying, founding, water quenching, ball milling, drying and sieving, pressing the glass solder powder into sheets, and presintering for densification; placing the glass solder sheets between the two to-be-welded ceramics for assembly; and putting the assembled sample into a muffle furnace, heating to a welding temperature, keeping the temperature for a certain time, and cooling along with the furnace. The glass solder comprises the components in percentage by weight: 30%-38% of CaO, 20%-26% of TiO2, 5%-10% of REO, 1%-5% of B2O3 and 34%-44% of SiO2. According to the method, brazing seams existing in a traditional glass connection method can be eliminated, uniform mixing of the glass solder and ceramic crystal grains is achieved, and then the strength, the thermal shock resistance and the high temperature resistance of a connector are improved.
本发明公开了一种玻璃焊料渗透连接氧化锆陶瓷的方法，属于焊接技术领域。该方法是将两块待焊氧化锆陶瓷表面打磨抛光平整；按球磨‑烘干‑熔制‑水淬‑球磨‑烘干‑过筛路线制备玻璃焊料粉体，玻璃焊料粉体压制成片状，并预烧结致密化；将玻璃焊料片放置于两块待焊陶瓷之间装配；将装配好的样品放入马弗炉中加热至焊接温度，保温一定时间后随炉冷却。所述玻璃焊料的组分为：CaO：30％～38％，TiO2：20％～26％，REO：5％～10％，B2O3：1‑5％，SiO2：34％～44％。本发明能够消除传统玻璃连接方法存在的钎缝，实现玻璃焊料和陶瓷晶粒的均匀混合，进而改善接头强度、热震抗力和耐高温性。
