In view of the poor solderability of metallic film formed on ceramic surface, a secondary metallization of ceramic surface by nickel plating was advanced.
为提高陶瓷金属化层的焊接性能，提出了一种陶瓷二次金属化镀镍工艺。

The experimental procedures of the post-treatment were investigated, and its effects on the metallization of PZT ceramic surface and the properties of the PZT ceramic components were discussed too.
