When the surface of aluminum comes into contact with the air, it will quickly react with the oxygen in the air to produce a dense aluminum oxide film. This reaction process is often considered to be “aluminum rusting”. But in fact, this film on the surface of aluminum is very hard and corrosion-resistant, and can tightly cover the surface of aluminum, preventing aluminum from further reacting with oxygen or water. Ya mere, the actual fact is that this self-protection mechanism of aluminum makes it not as easy to rust as iron.

What is the principle of aluminum rusting?

Aluminum is an active metal that reacts with oxygen in the air at room temperature. This reaction is called an oxidation reaction, and the result is a dense aluminum oxide film on the surface of aluminum. Ihe nkiri alumini oxide a siri ike na-eguzogide corrosion. Ọ na-akwadosi ike n'elu aluminom, na-egbochi aluminom n'ụzọ dị irè ka ọ ghara iso ikuku oxygen ma ọ bụ ihe ndị ọzọ na-emerụ emerụ, si otú ahụ na-echebe ndị esịtidem aluminum si ọzọ oxidation. Ọ bụ ezie na ihe nkiri aluminom oxide nwere mmetụta nchebe dị mma na aluminom, n'okpuru ụfọdụ ọnọdụ pụrụ iche, dị ka ncha ma ọ bụ mmebi n'elu aluminom, na-ekpughe ihe dị n'ime aluminom, ma ọ bụ aluminom nọ n'ọnọdụ siri ike dịka oke iru mmiri na oke okpomọkụ ruo ogologo oge, ọ nwere ike ime ka oxidation ọzọ nke aluminom, nke bụ ihe anyị na-akpọkarị “aluminom nchara”. Ụkpụrụ nke nchara aluminom bụ na aluminom na-emeghachi omume na oxygen na ikuku iji mepụta ihe nkiri aluminom oxide. This film has a good protective effect on aluminum and can prevent aluminum from further oxidation. Agbanyeghị, n'okpuru ụfọdụ ọnọdụ pụrụ iche, aluminum may still undergo further oxidation reactions.

How long does it take for aluminum to rust?

How long does it take for aluminum to rust? Aluminum can rust, but its rusting process is relatively slow. The rusting time of aluminum is affected by many factors, including environmental factors, material processing and usage conditions. Under normal circumstances, aluminum rusts relatively slowly, but aluminum that has been exposed to harsh environments for a long time or has not been properly treated is more likely to rust. Generally speaking, under normal circumstances, aluminum that has not been specially treated may take decades or even hundreds of years to show obvious rust.

Ọgwụgwọ elu: Ihe aluminom nke meworo ọgwụgwọ elu dị ka anodizing, electrophoresis, spraying, na electroplating nwere nnukwu ihe nkiri oxide na-eguzogide corrosion n'elu ha, nke nwere ike budata ịgbatị ndụ ọrụ nke aluminom.

Ọkpụkpụ na mmebi: Scratches and damage on the surface of aluminum will destroy the aluminum oxide film, making aluminum more susceptible to corrosion and rust.

Contact with electrolyte: Aluminom, as a conductive material, is prone to electrochemical reactions when in contact with electrolytes, thereby promoting the rusting process.

Storage conditions: Aluminum materials that are exposed to harsh environments for a long time, such as coastal areas or rainy areas, will rust faster.
