Embodiment 1

[0029] The preparation method of depositing cobalt on the anodized aluminum template of this embodiment is as follows:

[0030] (1) Pure aluminum surface pretreatment process: the pure aluminum material is cut, cleaned, degreased, and lye film removed in sequence;

[0031] (2) Put the pure aluminum pretreated in step (1) into the prepared malonic acid solution with a mass fraction of 1.0mol / L for anodic oxidation. The relevant parameters are time 4h, temperature 10°C, and voltage 140V;

[0032] (3) After anodized pure aluminum is depressurized to remove the barrier layer, it is rinsed with tap water, ultrasonically cleaned for 5 minutes, and then soaked in the film removal solution. The film removal solution is composed of phosphoric acid and chromium trioxide. Contains 10g of chromium trioxide, 10mL of phosphoric acid, the balance is water, soaking time 5h, temperature 60℃ for film removal treatment;

[0033] (4) After the aluminum sheet treated in step (3) is taken out, it ...

Embodiment 2

[0037] The preparation method of depositing cobalt on the anodized aluminum template of this embodiment is as follows:

[0038] (1) Pure aluminum surface pretreatment process: the pure aluminum material is cut, cleaned, degreased, and lye film removed in sequence;

[0039] (2) Put the pure aluminum pretreated in step (1) into the prepared malonic acid solution with a mass fraction of 1.0mol / L for anodic oxidation, and the relevant parameters are time 1h, temperature 20°C, and voltage 60V;

[0040] (3) After anodized pure aluminum is depressurized to remove the barrier layer, it is rinsed with tap water, ultrasonically cleaned for 5 minutes, and then soaked in the film removal solution.

Abstract

The invention belongs to the technical field of methods for depositing cobalt, and particularly relates to a preparation method for depositing the cobalt on an anodic aluminum oxide template. The method specifically comprises the following steps that (1) cleaning, oil removal and film removal treatment is performed on a pure aluminum surface; (2) pure aluminum is placed into oxidization liquid forprimary constant-pressure anodic oxidization; (3) the oxidized aluminum material is washed and is soaked in a film removal solution for film removal treatment, and the film removal solution is prepared from phosphoric acid, chromium trioxide and water; (4) the aluminum material is taken out, is cleaned and then is subjected to secondary anodic oxidization; (5) the oxidized aluminum material is placed into a reaming solution for reaming treatment; (6) the treated aluminum material is placed into a cobalt salt solution for deposition of the cobalt. The deposition amount of nano cobalt preparedwith the method is maximized, and the deposited cobalt is excellent in quality and high in stability.

Description

technical field [0001] The invention belongs to the technical field of methods for depositing cobalt, and in particular relates to a preparation method for depositing cobalt on an anodized aluminum template. Background technique [0002] With the development of social economy and the continuous emergence of various new technologies, anodized aluminum film has gradually entered people's field of vision. Compared with other templates, the anodized aluminum film has excellent performance in terms of corrosion resistance, high temperature and high pressure, and high chemical stability. main template. [0003] Over the past few decades, a great deal of research has been done on key techniques for electrodepositing metals. It mainly includes oxidation part and deposition part. In order to obtain a highly ordered porous structure of anodized aluminum, people have conducted a lot of research on the anodic oxidation conditions of metal aluminum by controlling and perfecting the se...
