This sounds like a home work question. But as I don't know what your teacher wants for an answer. I will discuss what I know.
Nickel is:A high hardness metal
Can be and is used in alloys
Is relatively inexpensive for its properties
Is very resistant to corrosion
Can be plated to other materials (The coating system most used in automotive)
This all makes it ideal to coat other materials to increase the wear resistance
In alloys it tends to make the material it is combined with harder wearing
All in all very useful
You can deposit nickel as a coating by using nickel chloride and a technique known as electroplating.
Nickel
used for nickel platting and other products that need a coating
theory of the propeller, compressors for combustion engines, rocket engines, Kaplan turbines, chrome-nickel steel, trans-oceanic ship with a diesel engine
No. U.S. quarters minted in 1965 and later are mostly copper with nickel coating.
The only nickel I can think of in a Corvette, would be in the engine bearing inserts.
Typically, especially in the early days of internal combustion engines, piston rings were made using specially hardened cast iron. Nowadays various alloys of hardened nickel/chrome steel are also used.
Electric Cars produce sulfur dioxide from their batteries. The manufacturing process of Nickel Metal Hydride (ex. Toyota Prius) and Lithium Ion (ex. Hyundai Sonanta Hybrid) batteries creates a lot of sulfur emissions. A conventional internal combustion engine vehicle actually emits less sulfur oxides to the atmosphere than electric and hybrid vehicles.
To make nickel earrings nickel-free, you can coat them with a layer of clear nail polish or a jewelry sealant to create a barrier between the nickel and your skin. Another option is to attach hypoallergenic earring hooks or posts to replace the nickel ones.
Inner Core. It is made of solid nickel-iron alloy.
Since 1965, U.S. quarters have been made of a solid copper core with a copper/nickel coating.
This is because modern pennies are not entirely copper, they are nickel with a copper coating.
