Abstract

The invention provides a metal surface anti-fingerprint treatment method. The metal surface anti-fingerprint treatment method comprises the following steps of preparing a metal base material, depositing an aluminum layer on the metal base material through a vacuum coating method, and carrying out thermal oxidation treatment on the aluminum layer to enable the aluminum layer to be oxidized into an alumina layer, wherein multiple nanometer mastoids are distributed on the alumina layer. The invention also provides a metal product prepared by the metal surface anti-fingerprint treatment method. The metal product comprises a metal base material and an alumina (Al2O3) layer formed on the metal base material, wherein multiple nanometer mastoids are distributed on the surface of the alumina (Al2O3) layer.

Description

technical field [0001] The invention relates to a metal surface anti-fingerprint treatment method and a prepared metal product. Background technique [0002] As 3C electronic products are used more and more frequently, consumers have higher and higher requirements for the appearance of products. In addition to the requirements of beautiful color and comfortable handle of the product shell, the surface is also required to have good wear resistance, scratch resistance, and anti-fingerprint (anti-fingerprint) performance. [0003] In order to improve the anti-fingerprint performance of the metal surface, US Patent No. 006736908 discloses an anti-fingerprint metal surface treatment liquid. The surface treatment solution contains special organic resin, soluble vanadium compound, and soluble metal compound, which contains at least one metal element among Zn, Ti, Mo, W, Mn and Ce. The metal surface treated by this treatment solution has good resistance Fingerprinting. However, t...
