Aluminum oxide ceramic surface metallization method
The invention relates to the technical field of ceramics, in particular to a surface metallization method of aluminum oxide ceramics, which comprises the following steps: mixing metal powder, auxiliaries and an organic carrier to prepare metallization slurry, printing the metallization slurry on an aluminum oxide ceramic matrix by adopting a silk screen, drying at 50-60 DEG C for 1-1.5 hours, and superposing another aluminum oxide ceramic matrix to form a'sandwich 'structure. After being pressed, the aluminum oxide ceramic is heated, degummed and sintered in the atmosphere of hydrogen and nitrogen, the tensile strength of the metallization layer and the aluminum oxide ceramic is tested, and the tensile strength of the metallization layer reaches 120 MPa or above.
本发明涉及陶瓷技术领域，具体为一种氧化铝陶瓷的表面金属化方法，将金属粉体、助剂、有机载体混合，制成金属化浆料，采用丝网将金属化浆料印刷至氧化铝陶瓷基体上，经50‑60℃干燥1‑1.5h后，再叠加一件氧化铝陶瓷基体，形成“三明治”结构，进行压制后，在氢气和氮气的气氛下升温排胶、烧结即可，对金属化层与氧化铝陶瓷的抗拉强度进行了测试，金属化层抗拉强度达到120MPa以上。
