Asked in Plumbing
Is it OK to connect brass pipe to chromed pipe?
No! That will create intergranular corrosion
Asked in US in WW2
List 6 types of corrosion that effect aircraft?
Galvanic, pitting, concentration cell, intergranular, stress cracking, Uniform etch, crevis corrosion
Asked in Math and Arithmetic, Chemistry
Why is intergranular corrosion considered dangerous in the metallic frames of the aircraft?
Because it weakens the molecular bonds binding the metal together - potentially leading to catastrophic failure !
Asked in Chemistry
What are the conditions for wet corrosion?
if the corrosion product goes into solution or evolved as a gas , the corrosion reaction go on unchecked

Sensitization of steel?
Sensitization happens when a stainless steel is held at an intermediate temperature (typically ~425 - 815 degrees Celsius) and chromium carbides precipitate at the grain boundaries. This precipitation of chromium carbides at the grain boundaries happens because the carbides are insoluble at these temperatures. In order for the carbide to precipitate, it must get chromium from the surrounding metal. This means that there is a chromium depleted zone around the grain boundaries. It should be apparent that this chromium depleted zone will be less corrosion resistant, specifically to intergranular corrosion. Sensitization is particularly important in metals that are welded. This is because the welding zone experiences temperatures in the range that can cause sensitization. This can cause localized intergranular corrosion at the weld site.

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.
Asked in Car Sounds, Car Batteries
Does pouring coke on car battery get rid of corrosion?
It will help, but a much better solution is to remove the battery cables, clean the connections and then use baking soda to neutralize the corrosion.
Asked in Acids and Bases
Will an acid cause corrosion?
Yes an acid can cause corrosion. It depends on the material considered and the concentration of the acid. The reaction involved in the corrosion process in acidic solution is the cathodic reduction of Hydrogen ion H+ to give Hydrogen gas H2. H+(solution) + electron -----> H2 (gas) the metal corrosion reaction is the anodic oxidation: Metal -------> Metal n+ + n electrons This is for example the corrosion process of Iron or Carbon Steel in contact with an acidic solution. Stainless Steel or Nickel alloy are more resistant to acid solution and are corrored only by some acids. V. Acids results in over $12 billion of corrosion related costs a year in mining, pulp & paper manufacturing, petroleum refining, and chemical manufacturing. Acid resistant plating (high phosphorus electroless nickel) is commonly used to limit corrosion in highly acidic environments.
What is a corrosive solution?
Any solution that is responsible for corrosion of substances is a corrosive solution. Most commonly we use iron's rusting as an example of corrosion which is formed by moisture in air. Some commonly known corrosive solutions are Hydrochloric acid, Iron(III) chloride, HF, Aqua fortis, Acetic acid, Hydroxylammonium nitrate, Aqua regia .
Asked in Metal and Alloys
Types of corrosion?
Corrosion can be categorized in some common types uniform corrosion pitting corrosion galvanic corrosion crevice corrosion concentration cell corrosion graphitic corrosion
Why is corrosion an electrochemical process?
Electrochemical Cells Corrosion is electrochemical in nature because the corrosive chemical reactions involve transfer of charge. Iron goes into solution as Fe++ ions. As these ions go into solution, the metal becomes negatively charged (by the electrons left behind) with respect to the electrolyte.
Can copper turning be used to test how pH affects copper corrosion?
If copper is present, the solution will turn blue...
Asked in Chemistry, Engineering, The Difference Between
What are the differences between E309 and E309L electrodes?
The "L" suffix signifies this is the low carbon variant on this grade. See the composition limits listed in the material standard ASME Section II Part C for stainless steels in SFA 5.4 and 5.9 The low carbon grade is often used to protect from intergranular corrosion.

What is corrosion in geography?
The chemical action on rocks by sea water and is most effective on limestone rocks which are carried away in solution.
When is corrosion useful?
Corrosion will be useful when you work on corrosion industry.
Asked in Chemistry, Chemical Engineering, Mechanical Engineering
Which is the best method for preventing corrosion and an accerate scale to measure the corrosion?
A method of preventing corrosion of metals using silanes. The method comprises applying a first treatment solution directly onto the surface of the metal, wherein the first treatment solution contains at least one multi-functional silane having at least two trisubstituted silyl groups, and wherein the substituents are individually chosen from the group consisting of alkoxy and acetoxy. An optional second treatment solution containing an organ functional silane may also be employed, particularly if the metal is to be painted.

What is a good solution for dissolving rust or corrosion?
muriatic acid - - - - - phosphoric acid is very commonly used. It can be had as a paste called "Naval Jelly."
How does dissolved oxygen affect corrosion?
The '''more''' dissolved oxygen in the elctroylte (solution) the '''more''' corrosion. Because if there is more dissolved oxygen, then there is more hydrogen ions, therefore the metal is more likely to corrode if it is exposed to more hydrogen ions. Therefore more electrochemical exchange, the hydrogen ions will pass into the metal, and the metal will lose electrons to the solution.
