Preparation method of aluminum oxide metallized ring
The invention discloses a preparation method of an aluminum oxide metallized ring in the technical field of ceramic material processing, which comprises the following steps: S1, lathing: lathing a formed ceramic ring; s2, printing, drying and sintering: selecting one surface of the turned ceramic ring as a surface A and the other surface of the turned ceramic ring as a surface B, performing metallization printing on the surface A, drying the surface A, and putting the surface B of the ceramic ring downwards in a molybdenum wire furnace for primary sintering; after primary sintering is completed, metallization printing is conducted on the surface B, drying is conducted, and then the surface A of the ceramic ring is placed in a molybdenum wire furnace downwards to be subjected to secondary sintering; s3, metallization and re-leveling are conducted, specifically, the first corundum setter plate is placed at the upper end of a push plate of a molybdenum wire furnace, the ceramic ring obtained after secondary sintering is flatly placed at the upper end of the first corundum setter plate, a press-burning plate with the preset weight is placed at the upper end of the ceramic ring, and the heating and re-leveling process is conducted; according to the method, the warping degree problem of the annular aluminum oxide thick film after metallization sintering is solved, and the large-size annular aluminum oxide thick film metallization structural part with excellent flatness and warping degree can be manufactured.
本发明公开的是陶瓷材料加工技术领域的一种氧化铝金属化环制备方法，包括以下步骤：S1:车加工，将成瓷的瓷环进行车加工；S2:印刷、烘干及烧结，选取完成车加工的瓷环的一面为A面，另一面为B面，对A面进行金属化印刷后烘干并将瓷环B面向下置于钼丝炉中进行一次烧结；完成一次烧结后，对B面进行金属化印刷后烘干后将瓷环A面向下置于钼丝炉中进行二次烧结；S3:金属化复平，将第一刚玉承烧板放置于钼丝炉的推板上端，将二次烧结后的瓷环平放在第一刚玉承烧板上端，在瓷环上端放置有预设重量的压烧板，进行升温复平过程；本发明解决环状氧化铝厚膜金属化烧结后的翘曲度问题，能够制成平面度、翘曲度优异的大尺寸环状氧化铝厚膜金属化结构件。
