Problems solved by technology

[0006] However, in the case of the above prior art 1, since a region that can easily cause an oxidation reaction or a region that cannot cause an oxidation reaction is removed and etching is performed depending on whether the oxidation reaction proceeds to form a pattern, there is no specific disclosure based on the oxidation reaction. degree while the pattern has a variety of colors and provides an aesthetic method

Embodiment 1

[0100] 1. Oxidation degree control pattern is formed on the metal substrate

[0101] After the carbon tape is attached to the copper sheet, the surface of the copper sheet to which the carbon tape is attached is subjected to a low-temperature heat treatment at 40° C., so that the carbon-based organic matter of the carbon tape remains, and the carbon tape is torn off to form an oxidation degree control pattern.

[0102] 2. Form coating film

[0103] On the copper sheet where only the carbon-based organics remain, the TiO 2 Sputtering was performed for 30 minutes to form a coating film.

[0104] 3. Accelerated oxidation treatment

[0105] The surface of the thin copper plate on which the coating film was formed was subjected to a high-temperature heat treatment at a temperature of 250° C. for 30 minutes.

Embodiment 2

[0107] Except that the temperature of the low-temperature heat treatment stage was set to 50° C., it was performed in the same manner as the method of Example 1 above.

Embodiment 3

[0109] Except that the temperature in the low-temperature heat treatment stage was set to 60° C., it was performed in the same manner as the method of Example 1 above.

Abstract

An embodiment of the present invention provides a color metal comprising: a metal substrate comprising a first metal; an oxidation degree control pattern disposed on the metal substrate, the oxidationdegree control pattern increasing or decreasing the oxidation degree over time of the first metal; and a coating film disposed on the metal substrate on which the oxidation degree control pattern hasbeen disposed, wherein a first region of the metal substrate, on which the oxidation degree control pattern is present, and a second region of the metal substrate, on which the oxidation degree control pattern is not present, display different colors due to a difference in oxidation degree over time.

Description

technical field [0001] The present invention relates to active metals and methods for their manufacture. It relates in more detail to a reactive metal having a pattern that changes in color over time due to the degree of oxidation and a method of manufacturing the same. Background technique [0002] Recently, as the demand for metal designs has increased, metal designs have been used in various fields such as the construction field, the field of electronic components, and the field of daily necessities. In particular, in the field of architecture, studies are being conducted in various aspects regarding the metal design of the appearance of home appliances, etc., which play an important role in the field of exterior materials and interior design. [0003] However, in the case of metal products using conventional casting techniques or forging techniques, there is a problem that the colors of metals that can be produced using this technique are limited. Therefore, it is pref...
