Sea spray

Sea spray is a spray of seawater that forms when ocean waves crash, or high winds are blowing.

Make up[edit]

Salt spray contains a high concentration of mineral salts, particularly chloride ions.

Effects[edit]

Salt spray is largely responsible for corrosion of metallic objects near the coastline, as the salts accelerate the corrosion process. Salts do not dissolve in air directly, but are suspended as fine particulates, or dissolved in microscopic airborne water droplets.

Chemical resistance[edit]

The salt spray test is a notable measure of material endurance, particularly if the material will be used outdoors and must perform in a mechanical load bearing or otherwise critical role. These results are often of great interest to the marine industries, whose products may suffer extreme acceleration of corrosion and subsequent failure due to the salt water environment.
