High-strength ceramic metallization method
The invention discloses a high-strength ceramic metallization method, which innovatively obtains a ceramic grain growth agent, and the ceramic grain growth agent comprises 75-85 wt% of metal oxide powder A, 5-10 wt% of a binder A and 5-20 wt% of a solvent A. The method comprises the following steps: coating the ceramic grain growth agent at a to-be-metallized position of an aluminum oxide ceramic matrix, sintering, and carrying out sintering to obtain the high-strength ceramic metallization material. Therefore, a double-layer structure of fine grains and coarse grains is formed on the ceramic matrix, the fine grains on the inner layer play a role in improving the strength of the ceramic matrix, and the coarse grains on the surface layer can improve the osmotic pressure of a glass phase in the ceramic matrix during subsequent metallization sintering, so that the glass phase in the ceramic matrix is promoted to permeate into a metallization ink layer; and the bonding strength of the metallized ink layer and the ceramic substrate is improved, so that the subsequent sealing strength of the ceramic substrate and the metal piece is ensured.
本发明公开一种高强度陶瓷金属化的方法，创新得到了一种陶瓷晶粒增长剂，该陶瓷晶粒增长剂包括75wt％～85wt％金属氧化物粉末A、5wt％～10wt％粘结剂A以及5wt％～20wt％溶剂A，通过先在氧化铝陶瓷基体需要金属化的位置涂覆陶瓷晶粒增长剂，经过烧结后，从而在陶瓷基体上形成细晶粒和粗晶粒双层结构，内层的细晶粒起到提高陶瓷基体强度的作用，而表层的粗晶粒在后续金属化烧结时，能够提高陶瓷基体中玻璃相的渗透压，促进陶瓷基体中的玻璃相向金属化油墨层中渗透，提高金属化油墨层和陶瓷基体的结合强度，从而保证后续陶瓷基体与金属件的封接强度。
