Embodiment Construction

[0009] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0010] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features that are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0011] An aluminum alloy surface oxidation treatment process is characterized in that it comprises the following steps:

[0012] 1) Put the aluminum alloy workpiece in the electrolytic tank, and then add the electrolyte with a pH value of 10-11. The electrolyte is composed of silicate 12-13g / L, boric acid 5-7g / L, potassium hydroxide 0.3 ~0.5g / L, hydrogen peroxide 15~20g / L, SiC 0.3~0.6g / L, stabilizer 0.2~0.7g / L, and the rest is water, and the workpiece is electrolyze...

Abstract

The invention discloses an aluminum alloy surface oxidation treatment process. The process is characterized by including the following steps of 1, placing an aluminum alloy workpiece in an electrolytic bath, adding an electrolyte with the PH value ranging from 10 to 11, and electrolyzing the workpiece to obtain an oxidation film, i.e., the electrolyte per liter comprises 12-13 g of silicate, 5-7 g of boric acid, 0.3-0.5 g of potassium hydroxide, 15-20 g of hydrogen peroxide, 0.3-0.6 g of SiC, 0.2-0.7 g of a stabilizer and the balance water; and 2, washing the electrolyzed workpiece for 2 min with tap water, and then polishing the workpiece till the workpiece is smooth. The surface treatment method is innovative, reasonable, easy to implement, high in environment friendliness and worthy of popularization, and the performance of finished products is excellent.

Description

technical field [0001] The invention relates to the field of surface treatment, in particular to an aluminum alloy surface oxidation treatment process.
