    摘要： The present invention relates to a method for preparing plastic particles coated with metal, which comprises the following steps. First, mix a plurality of plastic particles with a tin/palladium solution to form a first mixed liquid. Alternatively, first mix the plurality of plastic particles with a stannous chloride/hydrochloric acid solution. Then mix the plurality of plastic particles adsorbing the plurality of stannous ions with a palladium chloride/hydrochloric acid solution and form the first mixed liquid. Next, microwave the first mixed liquid so that the tin/palladium colloidal particles coat the plastic particles and thus forming first metal particles. Afterwards, mix the first metal particles with an electroless nickel solution and form a second mixed liquid. Metal nickel then coats the first metal particles and forming a plurality of second metal particles. Use microwave to activate the plurality of tin/palladium colloidal particles adsorbed on the surfaces of the plastic particles, and hence increasing adsorption of the plated metal layer on the surfaces of the plastic particle. Thereby, roughness and peeling-off of the plated metal layer can be reduced.

    摘要： A method for preparing a surface modification coating of metal bipolar plates is disclosed, which comprises the following steps: providing a metal substrate; pre-treating the metal substrate by substrate processing, depositing a Ni-based alloy layer on the metal substrate, or the combination thereof to form an activated layer on the surface of the metal substrate; packing the metal substrate in a powder mixture comprising permeated master metal, an activator, and filler powders; heat-treating the metal substrate in the powder mixture to allow the permeated master metal to diffuse into the activated layer and then to form a surface modification coating. The permeation rate of the permeated master metal can be increased due to high defect concentration of the activated layer. Hence, a corrosion-resistant surface modification coating is prepared at a low temperature, and it can decrease the interface contact resistance between the metal bipolar plates and gas diffusion layers.

    摘要： An improved plating method in combination with a low-temperature thermal treatment is disclosed. The method for reducing the stress in the nickel-based alloy plating comprises the steps of: (a) adding ceramic particles into a plating bath containing soluble nickel salts; and (b) placing a substrate in the plating bath and thereafter carrying out a pulse-current electroplating in the plating bath. The method of this invention can prevent substrate softening or deformation problems. The use of a post low-temperature thermal treatment can slightly increase the hardness of the coating products. The use of the low-temperature thermal treatment can reduce the stress of the coatings since the hydrogen embrittlement resulting from exist of hydrogen in the coatings is eliminated.
