Abstract
The invention discloses a novel aluminum alloy material. The novel aluminum alloy material is composed of aluminum, grapheme, copper, iron, zinc, nickel, manganese, chrome, lithium, germanium and silicon. The novel aluminum alloy material is coated with the grapheme, and is high in strength, good in light transmittance, high in electric and thermal conductivity, high in heat resistance, waterproof, rustproof and broader in application range. The novel aluminum alloy material can be applied to the low-concentration detection for medical care, fuel cell electrodes and solar cells. The additional value of aluminum alloy is increased, and the economic benefit is improved. The addition of rare earth elements is reduced through the grapheme coating, and the cost is reduced. Cold jet milling which is suitable for high-hardness alloy materials is adopted, so that the milled grain size is small and the cost is low. The process that mixed powder is sintered to be in a cylindrical shape through a spray forming method is simple, and the working procedures of conveying and compaction of the powder in a traditional process can be reduced. Vitamin C is taken as a reducing agent, and the vitamin C is not only no harm to humans, but also friendly to the environment.
