A method of attaching leads (18) to a porous metal material (14) comprises the steps of: (a) mechanically and electrically contacting the porous metal material (14) with a first terminal means (24) for applying an electrical potential to the porous metal material (14); (b) providing adjacent the porous metal material (14) a lead (26) to be attached which is attached to a second terminal means for applying an electrical potential to the lead (26); (c) applying an electrical potential across the first terminal means (24) and the second terminal means; and, (d) applying a driving force (F) to the lead (26) sufficient to impact and continue to press against the porous metal material (14) sufficiently to complete an electrical circuit between the first terminal means (24) and the lead (26) through the porous metal material (14). The electrical potential and the driving force are sufficient to create a plasma (36) of the porous metal material adjacent the lead (26) and to fuse the lead (26) with the porous metal material (14). This technique is particularly useful in the production of capacitors (10). |
