A salt spray chamber: what is it?

salt spray chamber

A salt spray chamber is generally used to measure the resistance of coated objects vs qqA ions. The equipment creates a highly corrosive environment for testing the long-term effects of salt on objects and materials. The coatings can be painted or electroplated, including chrome-plated or electroplated items. These testers are very useful in the metal industry.

How to test?

You need to place the sample to be tested in the chamber and spray the object to be tested with a fine mist of salt water. The number of times you have to spray, the chamber temperatures, etc. will vary according to the object being tested. After the test is over, the sample is removed and the degree of corrosion is recorded.
If necessary, scratch the object with a sharp knife and measure the width of the corroded surface before starting the test. The best coating will prevent rust from spreading from the bottom up.

Salt spray chambers are generally used to evaluate the corrosion properties of the following:

  • Galvanized
  • Galvanic Color Chrome, Nickel, Copper, Tin
  • Chemical conversion paint (zinc flake paint)
  • Organic color
  • Paint color
  • In the metal industry, salt spray testing is a typical corrosion testing technique. Typically, metals, polymers, and perhaps other types of materials are examined, and surface coatings are intended to shield the underlying metal from corrosion to some extent. By subjecting the coated sample to a corrosive attack, the salt spray test accelerates corrosion and determines (nearly relatively) if a coating is suitable as a protective coating. After some time has passed, the appearance of corrosion products such as rust and other oxides is assessed. The amount of time needed to complete the test often depends on how well the coating resists corrosion. In general, testing for corrosion/rust will take longer the more corrosion-resistant the coating is. One of the most popular and well-known corrosion tests is the salt spray test. ASTM b117 was the first salt spray standard that was acknowledged globally. ISO 9227, JIS Z 2371, and ASTM G85 are further significant applicable standards.

    A standardized and popular corrosion test method for determining the corrosion resistance of materials and surface coatings is the salt spray test. The test chamber is intended for a variety of corrosion experiments where the sample environment’s temperature must be kept within predetermined limits while it is wet. The test chamber for the salt spray is an enclosed area. There are pumps, drains, and nozzles inside. To make sure products can endure the effects of salty and humid climates, they test them using one before placing them in marine or coastal areas. A thin mist of salt water begins to fall over the sample as soon as the pump is turned on. Take a sample, and look for damage after the allotted time has passed.

    What are the features to look out for when buying a salt sprayer?

    Find out what your competitors and industry leaders are buying to meet their corrosion testing needs. This allows us to be at their level or above in making quality products. Conduct a detailed competitive analysis and find the top manufacturers in your city or country.

    From where should I buy these types of equipment?

    There are many reputed places that sell these types of equipment but you must buy them from a verified and trustable manufacturer. Testronix has been in the market for some years and has gained a good reputation for delivering high-quality products.
