Metallization process of aluminum oxide ceramic
The invention relates to the technical field of ceramic metallization processing, in particular to an aluminum oxide ceramic metallization process, which comprises the following steps: dipping aluminum oxide ceramic in molybdenum/aluminum gel to cover a layer of gel on the surface of the aluminum oxide ceramic, taking out, drying and roasting to obtain a preform, carrying out magnetron sputtering on the preform, and then carrying out nickel electroplating treatment and heat treatment. After the aluminum oxide ceramic is treated through the metallization method, better brazing performance is obtained, the surface brazing layer has high adhesive force, and the tensile strength can reach 64-67 MPa.
本发明涉及陶瓷金属化加工技术领域，具体为一种氧化铝陶瓷的金属化工艺，将氧化铝陶瓷于钼/铝凝胶中浸渍，使氧化铝陶瓷表面覆盖一层凝胶，取出后干燥、焙烧，得到预制体，将预制体进行磁控溅射后再进行电镀镍处理、热处理即可，氧化铝陶瓷经过本发明金属化方法处理后，获得了更好的钎焊性能，表面钎焊层具有较高的附着力，且抗拉强度能够达到64‑67MPa。
