【Abstract】 The process of nickel plating was introduced in this paper. Methods of eliminating the adhesion agent on carbon fiber were described, The relationship between weight increasing ratio of carbon fiber or resistance changing ratio of carbon fiber with current intensity,plating time was studied, and the technical conditions of nikel plating were obtained by orthogonal experiment. The results show that the adhesion is eliminated completely by the method of burning 5 min at 400℃ and the deposit quality is stable under 100 mA /dm2 current ,6min time providing . The nickel deposit of carbon fiber obtained by this method is uniform ,compact,adhesive and has good conductance.更多还原
