Abstract:
A method for selective metallization of a surface of a polymer article is provided. The polymer article contains a base polymer and at least one metal compound dispersed in the base polymer. The method includes gasifying at least a part of a surface of the polymer article by irradiating the surface with an energy source, and forming at least one metal layer on the surface of the polymer article by chemical plating. The metal compound contains a tin oxide doped with at least one doping element selected from a group including: V, Sb, In, and Mo.
Abstract:
A method of joining an amorphous alloy material to a heterogeneous material and a composite formed by the same are provided. The method comprises steps of: placing a pre-formed piece made of one of the amorphous alloy material and the heterogeneous material into a mold; heating the other of the amorphous alloy material and the heterogeneous material to a predetermined temperature, and casting the other of the amorphous alloy material and the heterogeneous material into the mold to form a transition connection part joining the amorphous alloy material to the heterogeneous material and having a fusion welded structure, a microstructure reinforcing connection structure and a composite connection structure; and cooling the amorphous alloy material and the heterogeneous material at a rate higher than a critical cooling rate of the amorphous alloy material to obtain a composite formed by joining the amorphous alloy material to the heterogeneous material by the transition connection part.
Abstract:
Metalized plastic substrates and a manufacturing method thereof are provided herein. The method includes providing a plastic substrate made of a plastic material, in which a plurality of accelerator particles is dispersed. The accelerator particles are made of a compound selected from the group consisting of: CuFe 2 O 4-6 , Ca 0 . 25 Cu 0.75 TiO 3-² , and TiO 2-à , and ´, ², à is deemed to be 0.05‰¤´‰¤0.8, 0.05‰¤²‰¤0.5, and 0.05‰¤Ã‰¤1.0. The method includes the step of removing plastic material in a determined area of a surface of the plastic substrate. The method further includes plating the exposed surface of the plastic substrate to form a first metal layer, and then plating the first metal layer to form a second metal layer.
