Title:
ARTICLE HAVING METALLIC SURFACE, TONE-TREATMENT METHOD THEREFOR, AND GAS PHASE OXIDATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/142487
Kind Code:
A1
Abstract:
The present invention improves rubbing fastness after a tone treatment has been performed on an article having a base material where at least the surface is composed of copper-zinc alloy. The present invention also provides a tone-treatment device that makes it possible to keep the amount of water used lower than with a wet treatment. Provided is an article having a base material 11 where at least the surface is composed of a copper alloy containing zinc, and an oxide layer 12 adjacent to the base material 11 surface, a ratio A of the mean zinc concentration to the mean copper concentration in a range of the depth of 10 to 20 nm with reference to the oxide layer 12 surface being higher than a ratio B of the mean zinc concentration to the mean copper concentration in the base material 11 surface. Also provided is a gas phase oxidation device for carrying out a tone-treatment method, the gas phase oxidation device being provided with: a gas phase reaction chamber 115 having an entrance and an exit and carrying out gas phase oxidation; and a conveyance mechanism 122 with which an elongated member, at least a part of which is provided with a portion where at least the surface is composed of metal, enters from the entrance, passes through the inside of the gas phase reaction chamber 115, and continuously comes out from the exit.
