Abstract

The invention provides an artificial brushed nickel appearance and anti-tarnish surface treatment method for a metal base material and a metal decorative assembly obtained by the method. The method provided by the invention comprises the following steps: polishing and drawing the metal base material by virtue of an abrasive tape, adhering a layer of protective film to effectively prevent the drawn metal base material surface from rusting; removing the protective film, removing glue and oil by a vacuum ultrasonic hydrocarbon solvent; carrying out vacuum microwave drying, so that the metal base material is not injured, and no three wastes are discharged; sequentially applying a physical gas-phase deposition layer, an ion glow activation layer, a non-reacting deposition layer and a reacting deposition layer, effectively improving the adhesive force and the appearance chromatism between the coating and the metal base material; and finally, spraying transparent powder. The appearance of the sprayed metal decorative assembly does not change color due to high-temperature baking, so that the antiseptic property, the anti-tarnish property and other properties of the metal base material can be effectively improved.

Description

technical field [0001] The invention relates to a surface treatment method for a metal base material, in particular to a surface treatment method for imitating the brushed nickel appearance and preventing discoloration on the metal base material. Background technique [0002] At present, iron-based accessories are mechanically polished and wire-drawn to form wire-drawn lines. After cleaning, physical vapor deposition (PVD) vacuum coating is performed. The coating is only micron-sized. darken. [0003] The problem of discoloration is also easy to appear in the decorative imitation brushed nickel green coating on the iron substrate, and it cannot be solved from the coating process. No matter whether it is water-based polishing and then mechanical drawing, or dry polishing and then drawing, it will be cured at the coating temperature. Finally, iron substrates are very easy to darken. [0004] In order to overcome the above problems, one of the feasible methods is to directly ...
