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 !
What are corrosion abrasion solution and attrition all types of?
swash
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 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 .
When is corrosion useful?
Corrosion will be useful when you work on corrosion industry.
Is it OK to connect brass pipe to chromed pipe?
No! That will create intergranular corrosion
List 6 types of corrosion that effect aircraft?
Galvanic, pitting, concentration cell, intergranular, stress cracking, Uniform etch, crevis corrosion

What has the author Arthur Horace Tuthill written?

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.

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.
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.
Can copper turning be used to test how pH affects copper corrosion?
If copper is present, the solution will turnblue...
