Salt Spray Testing: Corrosion Resistance Explained
Corrosion is one of the most common causes of material failure, especially in metals and coated surfaces exposed to harsh environments. Moisture, salt, humidity and chemicals can gradually degrade materials, affecting both their appearance and structural integrity. To prevent such issues, manufacturers rely on salt spray testing as a reliable method to evaluate corrosion resistance. Salt spray testing, also known as salt fog testing, is widely used to simulate corrosive conditions in a controlled environment. It helps determine how well materials and protective coatings can withstand exposure to salt-laden atmospheres over time. What is Salt Spray Testing? Salt spray testing is a standardized test method used to assess the corrosion resistance of materials and coatings. In this process, test samples are placed inside a chamber where a fine mist of salt solution is continuously sprayed. This creates an accelerated corrosive environment that mimics real-world conditions such as coastal e...
