Problems solved by technology

Existing aluminum products generally use multiple metal or alloy coating structures, but there are also disadvantages such as poor anti-corrosion performance, easy wear, and poor acid resistance, and it cannot effectively prevent electrochemical corrosion and other phenomena, and it also consumes a lot of precious metal resources. The production cost is high, and the use of a single anti-corrosion coating is far from ideal in terms of durability, gloss, hardness and anti-corrosion performance.

Description

technical field [0001] The invention relates to the technical field of aluminum-based composite materials, in particular to an anti-corrosion and durable aluminum product and a preparation method thereof. Background technique [0002] Aluminum metal is tough and light, ductile, and easy to conduct electricity. It can be used as a structural material for aircraft, vehicles, ships, ships, and rockets. However, pure aluminum is too soft, and its application range is limited, so people always add it to it. A small amount of copper, magnesium, manganese, etc., is made into aluminum alloy to improve the physical and chemical properties of aluminum. Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. However, aluminum alloys still have problems such as poor toughness, low hardness, no wear resistance, no impact resistance, ...
