What is salt spray corrosion test and what is the use of it?
The Salt Spray Corrosion Test is a procedure that has been standardized and is used to test the resistance of materials and coatings to corrosion. The test evaluates the capacity of the materials and coatings to withstand the corrosive effects of a salt-laden atmosphere, such as those found in marine or coastal areas. This helps determine how well the materials and coatings perform. The examination is carried out in a setting that is under strict supervision; normally, this takes place inside of a salt spray chamber. Inside of this chamber, the test specimens are subjected to a fine mist of salt spray solution. For the purpose of simulating a corrosive environment, the salt spray solution is produced by dissolving sodium chloride (NaCl) in distilled water. Additionally, the test chamber is kept at a certain temperature and level of relative humidity. The specimens are examined at certain intervals, and the test is carried out for the whole amount of time that has been determined.
