Coating corrosion performance can be evaluated while the coating is subjected to a corrosive atmosphere. One approach is to use a salt spray test in which a corrosive solution is atomised onto the test piece in an enclosed chamber. The salt spray solution can be neutral or modified to be more acidic for example.
An alternative approach is the saline droplet corrosion test, where a pattern of discrete droplets of a specified test solution are placed on the surfaces being tested. The test specimen is stored in conditions of high humidity, and the test solution reapplied only when it is needed to maintain the pattern of droplets.
Some standards relative to corrosion testing in a corrosive atmosphere are:
