Figure 3 is a perspective view of the appearance of a preferred embodiment of the present invention.

In order to understand the technical features and practical effects of the present invention in detail, and in accordance with the present invention, the following is a detailed description of the preferred embodiment of the present invention. The preferred embodiment is as shown in FIG. 1 . The tool surface marking method includes a first cleaning step, a first plating step, an ion water cleaning step, a drying step, a printing step, and a second cleaning step. a second plating step and a third plating step.

The first cleaning step: the rough embryo of a tool 10 is cleaned with water, and impurities such as dust and fines on the surface of the tool 10 can be removed.

The first plating step: the surface of the tool 10 is plated with nickel such that the surface of the tool 10 forms a first protective layer 20.

Ion water washing step: spraying ionic water generated by a general ion water machine on the surface of the tool 10, thereby cleaning the sulfide on the surface of the tool 10, and ions in the ion water are attached to the capillary holes of the first protective layer 20 to form An ion mask 30.

Drying step: drying the ionized water on the surface of the tool 10 to harden the ion film 30.

Printing step: printing a printing pattern 40 on the surface of the ion mask 30, the printing pattern 40 may be a letter or a pattern, because the printing pattern 40 will adhere to the ion film 30, and the printing adhesion of the printing pattern 40 is improved. The printed pattern 40 is not easy to fall.

The anode cleaning step: the surface of the tool 10 is cleaned by means of an anode. The anode is cleaned by placing the tool 10 into an electrolyte, electrically connecting the tool 10 to the anode, and energizing the anode. The surface of the tool 10 and the metal cation in the printed pattern 40 are dissolved, and the metal cation is attracted by the anion in the electrolyte, and the metal cation in the surface of the tool 10 and the printed pattern 40 is moved into the electrolyte, thereby the tool 10 surface and cation removal of the surface of the printed pattern 40.

The second cleaning step: the printing pattern 40 is cleaned with water, the acidity of the printing pattern 40 is faded, and the dirt around the printing pattern 40 is cleaned.

a second plating step: nickel is plated on the outer surface of the ion mask 30 different from the printed pattern 40, so that a second protective layer 50 is formed on the outer surface of the ion mask 30 at the printing pattern 40, because of the foregoing The anode cleaning step causes the tool 10 to have no residual cations on the printing pattern 40 during the second plating step, and the anion on the printing pattern 40 also leaves the surface of the printing pattern 40 due to the plating principle during the second plating step. Therefore, the surface of the printed pattern 40 does not have any ions, so that no plating impurities are generated on the printed pattern, and the yield of the printed pattern 40 is increased, so that the printed pattern 30 is not easily peeled off.

The third plating step: the outer surface of the second protective layer 50 is plated with a layer of chromium, so that the outer surface of the second protective layer 50 is formed with a third protective layer 60.

The present invention mainly increases an ion water cleaning step between the first plating step and the printing step, so that the tool forms an ion mask 30 on the surface of the first protective layer, and the ion film 30 can increase the adhesion of the printed pattern 40. Let the printed pattern 40 not fall off easily.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any one of ordinary skill in the art can use the present invention without departing from the technical features of the present invention. Equivalent embodiments of the local changes or modifications made by the disclosed technology are still within the scope of the technical features of the present invention.
