What causes corrosion?
Basically, corrosion is a disintegration of a material. Corrosion is typically associated with rusting, but that is only one type of corrosion. Other types of corrosion include, erosion, cavitation, fretting, galvanic, thermo-galvanic, intergranular, pitting, and more. The main causes boil down to a few root causes, chemical reactions, friction and a lack of durability. Rust is a chemical reaction, there are more types of reactions than from water and air. Reactions from other metals, acids, etc. cause corrosion as well. Friction can cause stress cracking, fretting, and intergranular corrosion and erosion. Two pieces of metal that rub on each other can cause fretting and lead to corrosion. Or water running over a rock for a few hundred years can turn it into a smooth pebble. Durability is key. Some substances are harder than others, and thus harder to disintegrate. Automotive Solutions: powder coating and plating are common methods to prevent corrosion. Electroless nickel plating is common within parts like ABS sensor rings and gears. powder coating is used on pumps and tanks. zinc plating is often used on bolts and braces. Below is a link to a study on corrosion, its costs, causes and how to prevent it.
Why does corrosion rate of no value on localized corrosion?
in my opinion, the value of corrosion rate obtained from certain reading is generally determine general corrosion rate, regardless what type of corrosion occur on a specific surface. in localized corrosion, where only some spots on surface is exposed to corrosion and other may be covered by film and etc. From my time of study, still didn't fine any research that can determine corrosion rate of localized corrosion unless u have a really micro- instrumentation that can monitor corrosion on the localized spots..

Is alloys resist to corrosion?
Alloys can add corrosion resistance to a metal
Can enhanced chlorine level in fresh water lead to corrosion of stainless steel?
yes, it can not only lead to corrosion but a faster corrosion.
How can corrosion be reduced?
The corrosion on iron can be reduced by suitable thin layer of element to be electroplated.
What is fretting?
Fretting corrosion is a complex process which involve chemical corrosion and friction (by asperities, surface irregularities) between components in motion, fluids moving in tubes, etc.
What or 4 factors that effect corrosion?
1) stress corrosion 2) corrosion fatique 3) fretting corrosion 4) heat treatment

How Fretting corrosion is most likely to occur -?
Fretting corrosion is most likely to occur in situations where there is repetitive movement or vibration between two contacting surfaces. This movement can lead to the removal of protective oxide layers on the surfaces, exposing them to corrosion. It is common in mechanical components like bolted joints, bearings, and electrical connectors.

Which pollutant causes the greatest corrosion of steel structures?
Sulfur dioxide is one of the primary pollutants that can cause the greatest corrosion of steel structures. When sulfur dioxide reacts with moisture in the air, it forms sulfuric acid, which is highly corrosive to steel. This corrosion can lead to structural damage and deterioration over time.

What is fretting on a guitar and how does it affect the sound produced?
Fretting on a guitar is when a player presses down on a string against a fret to change the pitch of the note produced. This shortens the vibrating length of the string, resulting in a higher pitch. Fretting affects the sound by allowing the player to play different notes and chords, creating melodies and harmonies.
