The sea air has moisture in it, causing the metal to corrode faster.
Because there is more salt in the air from the sea winds; And we know that the mixture of salt and water makes metal rust.
Sea water can rust nails or other metals.
Because there is salt spray (wind spraying the sea water) near the sea which causes steel to rust.
When salt and water and air combine, it accelerates the oxidation, therefore making the car rust faster :)
Nails rust because of O2 or oxygen, when it reacts with metals inside the nail
The salt in the sea air oxidizes the metals Very similar to the way salt used on roadways in the northern states during winter causes corrosion on cars.
Rust in it's truest definition is Iron(III) Oxide, meaning the only metal that can "rust" is Iron. If you are asking, "What metals oxidize more quickly near the sea?" The answer would still be Iron or steel, which has Iron in it. Oxidation occurs when metals have chemical reactions with Oxygen in the air and water. Rust occurs when the Iron atoms lose a few electrons to the Oxygen atoms and deteriorates the structure of the molecules, creating weak points. Salt water and salty air allows ions to flow more easily from objects creating faster decay. Ships battle this natural process be attaching galvanic anodes to the hull of the ships, this anode can be made out of Magnesium, Aluminum, or Zinc and basically creates a magnet for the ions, from the Oxygen, to "attack" it instead of deteriorating the Iron. These anodes need replaced about every 6 months.
Living in colder climates that get more snow can cause your care to rust faster. The salt that highway departments typically use on winter roads can accelerate the rusting of automobiles.
The labrador sea is closer
All metals will rust to a certain extent, but metals such as gold and titanium are highly resistant to corrosion. Ships, boats and rigs are fitted with 'sacrificial' annodes sometimes, which are usually large lumps of zinc. These corrode in place of other metal parts and structures, meaning that the important metal parts are less likely to corrode.
Because of the Salt and water mixed together in the air. Its just like putting water and salt on Iron and letting it sit there for a while.
There's more water vapor and other gases which cause corrosion.In water, they just go faster. -Neo
