Salt Spray Chamber

A salt spray chamber is a piece of testing equipment used to evaluate the corrosion resistance of materials or coated samples exposed to a salt aerosol or mist. This method simulates the effects of salt corrosion in a controlled environment, providing a standardized way to measure how well certain products can withstand salt-heavy environments, such as marine or coastal areas, where salt Salt Spray Chamber corrosion is a common concern.

The basic principle involves filling the chamber with a saline solution, typically 5% sodium chloride (NaCl) dissolved in distilled water. This solution is then atomized by a nozzle into a fine mist within the chamber, where test specimens are exposed for a specified duration, which can range from a few hours to several days or more, depending on the test standard or specific research requirements.
