Usually, corrosion consists of a process called oxidation, which often takes the form of rust. In the case of iron, it occurs when oxygen makes contact with the metal, and the two combine. Corrosion can also occur by other processes, such as with microscopic organisms.

What is immersed corrosion?
Immersed Corrosion refers to a type of metal corrosion when the metal is immersed in a liquid.
Define electrochemical corrosion?
Electorchemical corrosion is corrosion that is sped up due to electron movement, within the chemicals.
Corrosion Science and Control?
corrosion science and control means the act of scientist prevent corrosion and find the way to control it
What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
What effect does acidic water have on ferrous pipe?
In general, corrosion is the result of water with a low pH (below 7.0). Such acidic waters have lots of hydrogen ions in the water to react with the electrons at the cathode, so corrosion in metal pipes and fixtures is enhanced. Acid water can often be identified by a sour taste, and it will also dry your skin and hair.
Explain dry corrosion with an example?
Dry corrosion occurs when the metal reacts with oxygen in the air.
What is the difference between dry and wet corrosion?
dry corrosion is taken place in the presence of gases whereas wet corrosion takes place in the presence of moisture in air
Prevention of dry corrosion?
Anodizing method can be prevented.
What is the electrochemical corrosion and explain the mechanism of rust forming in acid?
methanol-oxygen fuel cell
What is wet corrosion and galvanic corrosion?
The dry corrosion is the corrosion of the metal that takes place in the absence of conducting(aqueous) medium. The reaction between metal and oxygen (atmosphere) at elevated temperatures in perfectly dry conditions is an example of dry corrosion.
How magnetite layer is useful in boiler corrosion?
Magnetite Layer is developed after essential chemical treatment. For instance, hydrazine and sodium sulfite are the most broadly chemicals. The presence of this layer has as result the deceleration of corrosion attack in tube's surface. Moreover, when this protective layer is spoiled, then mechanism of corrosion is going to start.
Ford escape 2001 tailgate won't open?
A little more info would help.m Do you have tension on the handle? Does the window open. Was there signs of corrosion on the locking mechanism? I would try removing the interior panel to see if you can move the locking mechanism w/ a screw driver. A little more info would help Do you have tension on the handle? Does the window open.

What is difference between wet corrosion and dry corrosion?
Corrosion is occurs when a metal becomes wet or damp. A current flows through this, making the unmoving particles throught the steel to the more reactive parts on the surface. These are called anodes. The current returns from the more reactive parts, through it, and then back to the the more still parts. Where the current leaves the anode, rust forms. Wet corrosion happens when a metal or other material is wet or damp- (or can be caused through the mositure in the air) Dry corrosion is similar, however the difference is that it forms through the presence of gasses in the air
What causes the internal resistance of a dry cell to increase as time passes by?
Corrosion- Oxidation specifically where molecules are deposited on conductive materials.
Can keeping salt in your car trunk over winter cause corrosion to the inside of the car?
Keep it in a tight/dry container and you'll be fine.
When is corrosion useful?
Corrosion will be useful when you work on corrosion industry.
Is nitrogen in an atomic bomb?
Possibly and possibly not. It would depend on design. If it was used the most likely use would be as dry nitrogen to prevent corrosion.
