Description

A kind of Al alloy composite and preparation method thereof

Technical field

The invention belongs to aluminum alloy materials field, particularly relate to a kind of Al alloy composite and preparation method thereof.

Background technology

Metals maximum in the earth's crust is aluminium Al, and next is only iron, and aluminium accounts for 7.45% of whole earth's crust gross weight, almost more than iron one times.Aluminium is argenteous light metal (proportion only has 2.7).Pure aluminium is very soft, can be pressed into very thin paper tinsel.The electroconductibility of fine aluminium is fine, and again merrily and lightheartedly, people commonly use it to replace copper, and manufacture electric wire, especially when remote power transmission, multiplex aluminum steel replaces copper cash, can reduce the equipment such as electric pole.

Because fine aluminium is too soft, people are by adding a small amount of Cu, Mg, Mn etc. thus making hard aluminium alloy, and aluminium alloy is specious, slim and graceful and don't easy-to-rust, thus has purposes very widely.

The electrochemical equivalent of metallic aluminium is high (2.98Ah/g), cheap, good processability, is a kind of desirable anode material.

But because the corrosion speed of fine aluminium in alkaline electrolyte is too fast, easily produce a large amount of hydrogen, cause the faradic efficiency of anode extremely low; The surperficial oxide film covered of aluminium, causes aluminum anode overpotential to raise, makes fine aluminium real work voltage in alkaline medium lower, reduce the voltage efficiency of anode simultaneously.
