Abstract

The invention discloses an aluminum alloy surface treatment method of microarc oxidation combined with pulse electrodeposition hole sealing. The treatment method includes the following steps that (1),pretreatment; (2), micro-arc oxidation treatment; (3), cleaning treatment before hole sealing; (4), pulse electrodeposition hole sealing treatment and (5), test specimen post treatment. A pulse electrodeposition hole sealing device includes an electrolytic bath arranged on a base plate. The electrolytic bath contains a hole sealing liquid. A temperature sensor, an aluminum electrode, and the testspecimen are all soaked in the hole sealing liquid. The aluminum electrode is connected with the anode of a pulse power supply through a communication line, and an amperemeter is arranged between thealuminum electrode and the pulse power supply. The test specimen is connected with the cathode of the pulse power supply. According to the electrolyte, raw materials are easy to get, environmental pollution is small. The ceramic layer obtained is compact and smooth, the porosity rate is low, the decay resistance is prominent, and the binding force between the ceramic layer and a base body is good. The novel pulse electrodeposition hole sealing method is good in adhesiveness and obvious in hole sealing effect.

Description

technical field [0001] The invention belongs to a surface treatment method of an aluminum alloy material, and in particular relates to a surface treatment method of an aluminum alloy with micro-arc oxidation combined with pulse electrodeposition sealing. Background technique [0002] Compared with the largest industrial material—steel, aluminum and its alloys have the advantages of low density, light weight, high specific strength, good plasticity and formability, and their excellent electrical and thermal conductivity, so they are widely used in industry. Extensive, which makes aluminum and aluminum alloys become important metal materials next to steel, and play an important role in industries such as automobiles, machinery, aerospace, and electronics. [0003] However, some shortcomings of aluminum itself also limit the application of aluminum and its alloys in the national economy, such as low hardness of aluminum, poor wear resistance, poor corrosion resistance, low melt...
