Salt Spray Testing Machine

Salt spray testing is a technique for determining the corrosion resistance of coatings and materials used in the manufacturing of fasteners. An accelerated corrosive assault is created during salt spray testing to better anticipate how effectively the coating protects the metal.

The most common application of salt spray testing is to make rapid comparisons between predicted and actual corrosion resistance. In actuality, there is only a shaky link between the coating’s test duration and its actual predicted life. This is owing to the fact that corrosion is influenced by a variety of external variables, since it is not a straightforward process.

As a result, the most effective application of salt spray testing is on samples to determine a pass-or-fail grade and compare it to expectations. This is usually done as part of a quality control procedure or to see how successful a specific production method is.

Salt spray experiments are carried out in a sealed room. A spray nozzle is used to apply a salt water solution to a sample. A corrosive experiment is imitated with this thick salt water fog. The appearance of oxides is examined over a period of time, which is based on the corrosion resistance of a product. The longer it takes for the oxides to form, the more resistant the product is. For certain coatings, testing can take anything from 24 to 1,000 hours or more.
