| Why aluminum doesn't rust |

Did you ever wonder why airplanes never seem to rust, despite their constant exposure to rain, sleet and snow?
The quick answer is that most aircraft are made of aluminum -- a chemical element that seems to resist corrosion even when exposed to air and water.
But the fact is that pure aluminum reacts so readily with water that, according to the laws of chemistry, the aluminum shell of an airplane should actually dissolve in the rain.
![[Image: Bild-1-EN.jpg]](http://www.thick-aluminum-plate.com/images/Bild-1-EN.jpg)
Fortunately for the airline industry, when aluminum metal is placed in the atmosphere, a thin layer, known as aluminum oxide, forms on the metal's surface and acts like a protective, rust-resistant shield.
Scientists have long known that aluminum oxide does not corrode rapidly in water, but they have been unable to fully explain why.
Now, for the first time, researchers have shown that liquid H2O has a surprisingly potent effect when it comes in contact with the surface of a metal oxide, a finding that has industrial and environmental implications.
"Water actually changes the structure of the solid surface," says Gordon Brown, Jr., the Dorrell William Kirby Professor of Earth Sciences.
Writing in the May 12 issue of the journal Science, Brown, graduate student Thomas P. Trainor and collaborators from the University of Chicago and Lawrence Berkeley National Lab present the first atomic-level model of what happens when water and aluminum oxide meet.
Shifting atoms
Aluminum oxide consists of atoms of aluminum and oxygen bonded together.
But Brown and Trainor discovered that, when water molecules come in contact with aluminum oxide, the aluminum and oxygen atoms on the surface move apart -- in some cases separating by more than 50 percent compared to their normal molecular positions.
As a result, when the outer layer of aluminum oxide gets hydrated or wet, its
structure changes just enough to become chemically inert and thus unable to react rapidly with additional water molecules or atmospheric oxygen. This change in molecular structure is why aluminum oxide metal resists corrosion.
Brown notes that these findings have widespread applications for the multi-billion-dollar catalysis and semiconductor industries, which are concerned with the effects of atmospheric water on metal oxides used in chemical catalysts and silicon chips.
However, he adds, the real driving force for this research is the important role that hydrated metal oxide surfaces in soils and sediments play in removing toxic metals like lead, mercury, chromium, arsenic, and selenium from contaminated groundwater.
"Understanding the molecular structure of the particle surfaces with which these metals react is essential for determining how effectively they are removed from the environment, and hence how available they are to organisms, including humans.
"Now for the first time we have a picture of the molecular structure of one of these surfaces and a better idea of what controls its reaction with environmental contaminants," Brown concludes.
To conduct their analysis of the surface of hydrated aluminum oxide, researchers used the most powerful synchrotron x-ray source in the U.S. - the Advanced Photon Source located at the Argonne National Laboratory in Illinois.
"Our research required the brightest synchrotron x-ray source available," says Brown. "The biggest surprise is that we could do it at all."
The other co-authors of the May 12 Science article are Peter J. Eng, Mathew Newville, Steven R. Sutton and Mark L. Rivers with the University of Chicago's Consortium for Advanced Radiation Sources; and Glenn A. Waychunas of the Lawrence Berkeley National Laboratory.

| Why doesn't zinc and aluminium rust but corrode instead? |

Passivation refers to the spontaneous formation of an ultrathin film of corrosion products, known as a passive film, on the metal's surface that act as a barrier to further oxidation. The chemical composition and microstructure of a passive film are different from the underlying metal. Typical passive film thickness on aluminium, stainless steels, and alloys is within 10 nanometers. The passive film is different from oxide layers that are formed upon heating and are in the micrometer thickness range – the passive film recovers if removed or damaged whereas the oxide layer does not. Passivation in natural environments such as air, water and soil at moderate pH is seen in such materials as aluminium, stainless steel, titanium, and silicon.
Passivation is primarily determined by metallurgical and environmental factors. The effect of pH is summarized using Pourbaix diagrams, but many other factors are influential. Some conditions that inhibit passivation include high pH for aluminium and zinc, low pH or the presence of chloride ions for stainless steel, high temperature for titanium (in which case the oxide dissolves into the metal, rather than the electrolyte) and fluoride ions for silicon. On the other hand, unusual conditions may result in passivation of materials that are normally unprotected, as the alkaline environment of concrete does for steel rebar. Exposure to a liquid metal such as mercury or hot solder can often circumvent passivation mechanisms.

1.Traditional aluminum and aluminum alloy plating
Aluminum and aluminum alloy electrolysis in the electrolyte can form a coating, but the coating binding force is not strong, easy to peel. Therefore, aluminum can be first deposited in the aqueous solution containing zinc oxide compounds and then electroplating, this method is either zinc displacement or deposition. It is also possible to first obtain a thin porous oxide film on the surface of aluminum and aluminum alloys by anodizing the power supply to perform electroplating.
1.1General aluminum and aluminum alloy plating process
Aluminum and aluminum alloy electroplating processes are pre-plated, electroplated and post-plated. Pre-plating treatment is the most critical process related to the quality of electroplated products. Its main purpose is to remove the grease on the surface of aluminum and aluminum alloys, naturally forming an oxide film and other dirt.
Conventional general processes are: degreasing-washing-demineralization-washing-pickling-washing-activation-washing-primary zincation-washing-removal-zinc-washing-secondary zincation-washing-neutral nickel-plating-washing- Subsequent plating.
There is also a wave of the anodized film instead of zinc immersion process in the subsequent plating.
