Abstract:The plated Ni layer on PZT ceramics by electroless plating must be carried out a post-treatment,which involved a Ni-electroplating process and double step heat-treatments at 200℃in air and at 400~460℃ in N2 atmosphere respectively. 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.
