Ceramic heater and manufacturing method thereof
The invention discloses a ceramic heater which comprises a ceramic plate and a ceramic hollow shaft, a ceramic plate welding surface is arranged on the ceramic plate, a hollow shaft welding surface corresponding to the ceramic plate welding surface is arranged on the ceramic hollow shaft, and a pure aluminum metallization layer is arranged on at least one of the ceramic plate welding surface and the hollow shaft welding surface. A welding hole protrusion is arranged on at least one of the welding face of the ceramic disc and the welding face of the hollow shaft, the ceramic disc and the ceramic hollow shaft are mutually positioned through a set of ceramic positioning pieces, and a vacuum brazing pure aluminum welding layer is welded between the welding face of the ceramic disc and the welding face of the hollow shaft. The vacuum brazing pure aluminum welding layer and the pure aluminum metallization layer are connected into an integrated welding layer in a vacuum brazing melting mode. The invention further discloses a manufacturing method. The ceramic heater is high in cleanliness, free of impurity elements, good in air tightness and high in connection strength, and the same-material integrated welding layer is connected. The cost is low, a special pressurizing structure is not needed, and one-time complete process time is short; and post-welding processing is avoided.
本发明公开了一种陶瓷加热器，包括陶瓷盘和陶瓷空心轴，所述的陶瓷盘上设置有陶瓷盘焊接面，陶瓷空心轴上设置有与陶瓷盘焊接面相对应的空心轴焊接面，在陶瓷盘焊接面和空心轴焊接面其中至少一个焊接面上设置纯铝金属化层，在陶瓷盘焊接面和空心轴焊接面其中至少一个焊接面上设置有焊接孔隙凸起，陶瓷盘和陶瓷空心轴通过一组陶瓷定位件相互定位，陶瓷盘焊接面和空心轴焊接面之间熔接有一真空钎焊纯铝焊层，真空钎焊纯铝焊层与纯铝金属化层真空钎焊熔融式连接为一体式焊层。还公开了其制作方法。该陶瓷加热器，洁净度高无杂质元素，同材质一体式焊接层连接，气密性好，连接强度高。成本低，无需特殊加压结构，一次完整工艺时间短；无焊接后加工。
