Abstract

A procedure for depositing nickel or cobalt by chemical reduction of a metallization bath on the surface of an electrically conductive material that is not normally catalytic for the metallization bath, whose procedure is characterized by bringing the surface, before said metallization, in contact with a pretreatment solution of a reducing agent selected from the group consisting of alkali metal borohydrides, alkali metal cyanoborohydrides and aminoboranes and then contacting the surface with the metallization bath to produce the chemical reduction of nickel or cobalt on the surface .
