METHOD FOR TREATING COMPLEX SURFACE BY THREE-DIMENSIONAL MULTI-LAYER PLATING AND THREE-DIMENSIONAL COMPLEX SURFACE TREATED STRUCTURE BY METHOD THEREOF

摘要

The present invention relates to a method for treating a complex surface by three-dimensional multi-layer plating and a three-dimensional complex surface treated structure by the method for treating the complex surface. According to the present invention, the method for treating the complex surface by three-dimensional multi-layer plating includes: a metal texture step of adding a metal texture to a substrate surface by a mechanical process; a masking step of forming a masking layer on an uncoated area with a predetermined pattern; a substrate plating layer forming step of forming a substrate plating layer on an electrochemical plating layer; an intermediate plating layer forming step of forming an intermediate plating layer on the substrate plating layer; and a surface decoration forming step of forming a surface decoration coating layer on the intermediate plating layer. According to the present invention, the method and the structure can provide excellent three-dimensional decoration by adding beautiful three-dimensional visual, texture, touch, color, and gloss or matt finish to a surface of an external case, a cover, or a decorative component of a mobile device. Particularly, the method and the structure can form a decorative pattern with a sharp contour without delamination or detachment of a multilayer plating film, and can be efficiently applied to various substrates.;COPYRIGHT KIPO 2014
