Abstract

Tool surface treatment with low surface reflectivity and no environmental contamination in the manufacturing process.
The surface of a tool is covered with a nickel base layer composed of a semi-gloss layer, a total gloss layer and a porous layer, and a hard gunmetal color layer composed of a tin-nickel alloy formed on the surface. The hard gunmetal color layer 22 has a copper brown color close to black and has low reflectivity, so that it is easy to identify surrounding members in a dark working environment where the illumination does not reach sufficiently, and the base layer is exposed by wear. However, since the color tone with the base layer is close, it is inconspicuous and can maintain sufficient hardness.
In addition, since it is a nickel-based alloy layer, it does not handle harmful substances in its manufacturing process and has a low environmental impact.

Description

The present invention relates to the surface structure of a tool, and in particular, in the surface structure of the tool, the color and material of the outermost layer and the inner base layer adjacent to the outermost layer are equivalent, and a dark color that does not reflect light is formed. Relates to the surface structure of a tool with a gun metal color, high stability of the entire surface, and high practicality.

Currently, the surface treatment of tools requires indispensable hardening treatment, aesthetic improvement and rust prevention treatment, so electroplating must be performed, and rust prevention, acid resistance and alkali resistance must be applied to the tool surface. Is formed. However, most of the current plating layers are layers having a silvery bright surface, and the design having such a bright surface has the following drawbacks that cannot be overcome in terms of use, visual and practicality.
1 The bright surface of the tool surface is formed by electroplating work with heavy metals such as chrome plating, cadmium, mercury or lead, and the environment is polluted by electroplating work with heavy metals or harmful substances.
2 During maintenance in the factory, the position of the member to be attached or removed is very dark, and the surrounding area of the member is very dirty, so it does not reflect light, and when a tool with a bright surface is entered, The reflection of the light is very large, and the user of the tool cannot recognize the position of the member due to the reflection of the light, so that the tool can be quickly brought to the position of the member and cannot be removed or attached.
3 Currently, most tools have a silver-brilliant surface, and there is a limit to the distinction, and there are some that can be identified by installing color tape on the glitter surface of the tool or by enamel baking. They are just marks and are not practical enough.
4 It is difficult to repair when the structure of the bright surface of the tool is damaged or dirty. For example, if it is damaged, the non-brilliant surface of the interior will be exposed, and it will take time and money to re-plat. Other methods cannot be completely repaired and are not economically efficient.

In view of the above-mentioned drawbacks, the inventor of the present invention has a tool surface color that can meet the demands in the working environment, has a high surface stability, and a coating layer after fixing the color is very stable. A surface structure was devised.
