Embodiment 1

[0077] A stainless steel plate with a thickness of 0.4mm is used to stamp and form a stainless steel substrate of 0.4mm; an aluminum layer with a thickness of 50-60um is formed on the stainless steel substrate by vacuum sputtering, and the conditions of vacuum sputtering are: temperature 400 Above ℃, the average high-speed electron current is 20v, and the time is 20-30min. Perform anodic oxidation treatment on the aluminum layer to form an anodic oxidation layer with a thickness of 8-12 μm, and the conditions of anodic oxidation treatment are conventional oxidation parameters. At this time, the thickness of the remaining aluminum layer between the anodized layer and the stainless steel substrate is more than 30 μm to ensure adhesion. A shielding layer is formed on the upper surface of the anodized layer by spraying masking or high temperature protective film. Use ABB mechanical grinding or manual polishing to remove the anodized layer and aluminum layer other than the shieldi...

Abstract

The invention provides a stainless steel sheet, a preparation method and electronic equipment. The preparation method comprises the steps that 1, an aluminum layer is formed on the upper surface of a stainless steel substrate; 2, an anode oxidation layer is formed on the upper surface of the aluminum layer; 3, a shielding layer is formed on a presumptive area of the upper surface of the anode oxidation layer, and the parts, outside the presumptive area, of the anode oxidation layer and the aluminum layer are removed; and 4, the shielding layer is removed. Thus, a stainless steel appearance and an anode oxidation appearance can be simultaneously arranged on the upper surface of the stainless steel sheet, and on the basis that the stainless steel appearance of the surface of the stainless steel sheet is maintained, the stainless steel sheet is subjected to dyeing, specific pattern setting and other ornamenting; and accordingly, the appearance effect can be enhanced, and the surface treatment method for the stainless steel sheet is enriched.

Description

technical field [0001] The invention relates to the field of plate surface processing, in particular, to a stainless steel plate, a preparation method and electronic equipment. Background technique [0002] Metal sheets are widely used in electronic devices such as mobile phones and tablet computers due to their more beautiful texture, wear resistance and scratch resistance. Among many metal sheets, stainless steel has gradually become a hot spot in the research and application of metal sheets due to its high strength, hardness and corrosion resistance. [0003] However, the current stainless steel sheets and their preparation methods still need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] The present invention is based on the following findings of the inventors: the current surface treatment methods for stainless steel plates are limited and ...
