Corrosion testing is widely used and quality control testing is performed in quality assurance laboratories in the metal business. The mentioned tests were carried out in a salt spray chamber. The test is performed on ferrous metals and alloys. Also, this is done in the paint and coatings industry to ensure the quality of the coating that will provide long-term performance to ferrous metals. Corrosion phenomena may be a topic that can be ignored, but have many difficult effects on ferrous metals. In the salty environment we live in, these materials occasionally react with iron and initiate an oxidation reaction that converts ferrous ions into ferrous oxide.
Over time, this reaction can lead to complete destruction of the product. Oxidation of materials also contributes to microbial reactions, which can lead to complete destruction and failure of the product. To avoid these situations, the paint and coatings industry is working to improve the durability of their products and their coatings. This happens because the coating can restrict the ingress of moisture or any contaminants and cause corrosion. Additionally, low-quality coatings can be removed by exposing the surface to moisture and causing oxidation. Therefore, the quality of the coating needs to be tested by artificial accelerated salt spray test.
But before you start, you should understand how a salt spray Test Chamber works. It's important to test it the right way. Corrosion Test Chambers simulate interior saline conditions, even in an accelerated fashion. Start preparing the specimen. Samples can be fasteners or thin metal sheets coated with paint. If it's a fastener or something that isn't flat like a bolt, it can be done by tapping them with wire and then hanging them up with a very thin rod. The rods used to hang the nuts and bolts later remained in the chamber only as hangers. If samples are flat like metal sheets or plates, they can easily be fixed at specified angles on the sample-carrying area of the chamber.
After this, close the chamber firmly and set the parameters. The user can start the test by activating the salt spray and maintain the temperature, test cycle duration, etc.
