Most of the industrial products which are used on a large scale are manufactured by using metals. The metallic surfaces, which are prone to corrosion attacks from various sources should be treated and taken good care of, in order to make them last long.
Ferrous and non-ferrous metallic surfaces have high chances of getting destroyed by attacks from exposure to certain levels of humidity, acids, solutions, gases etc. Therefore, it is very important to protect them from corrosion attack by using good surface coatings which form the protective layer. A Salt Spray Test Chamber does just that.
It is possible to protect metallic surfaces from corrosion attack only if a proper corrosion resistant is applied and then tested for failures, in order to guarantee the durability of the product. Now-a-days, comparative quality control strategies are being adopted during the production stage itself as a proactive measure. The best known process, which is popular as corrosion resistant, is spraying vapor tests using various salt solutions as well as condensation water climates using salt spray test chamber. Powerful reactants are turned into mists which are spayed on to the surface of metals like steel, zamak or brass. The appearance of corrosion products (oxides) is evaluated after a period of time.
A salt spray test chamber is an enclosed chamber where concentrated solutions are spayed in mist form to check the resistance of metals. It is the most popular and standardized test method used to check corrosion resistance of coated samples. It is very affordable and delivers fast results. It also supports repeated experiments or test conditions. Hence, salt spray test chambers are widely used in industrial applications and commercial areas for the evaluation of corrosion resistance of finished surfaces or parts.
It is employed in automobile equipment testing, aircraft engineering and also in construction industries. Most of the metal surfaces will be coated with paint, primer, rust-preventive coatings etc. Salt spray test is also conducted on these coated surfaces to evaluate their resistance to corrosion and rust.
Modern day salt spray test chambers are designed in the best manner to meet all the testing standards and also the testing parameters like temperature, air pressure of the sprayed solution, preparation of the spraying solution, concentration, pH etc. The digital controls and user-friendly interface make it simple to use the complex processes involved in corrosion testing using a salt spray test chamber.
