Abstract
This invention relates to a structure on a bi-color rust-proof barrier layer of a tool head, mainly used to form a surrounding recessed section marked with indication of a size, a model, a trademark and the like on a surface of a tool head (a metallic object) so that the structure on the rust-proof barrier layer painted with the different two colors is provided between the recessed section and the peripheral surface, thereby highlighting the indication marked at the recessed section so as to increase the distinctions of said object from other object.
Claims3
A bi-color rust-proof barrier layer structure of a tool head, especially a bi-color rust-proof barrier layer structure of which a surface is formed with a strip of recessed surrounding section marked with a size, a model, trademark and the like, which is characterized in that a surrounding surface of the tool head and the strip of surrounding recessed section are in advance electroplated or dyed with the rust-proof barrier layer of a specified color and then the rust-proof barrier layer on the surface of the tool head is removed so that the strip of surrounding recessed section is still maintained with the color of the rust-proof barrier layer before treated;
- after the tool head is put in an electroplating bath for one more “electroplating on another barrier layer” or in a dyeing tank for one more “dying on another barrier layer” so that another colored barrier layer may be formed on the surface with a portion provided with the rust-proof barrier layer removed before, thereby allowing the color of the rust-proof barrier layer of the tool head serving as a foil to the different 2-color structure of the strip of surrounding recessed section.
