How does the surface coating prevent corrosion?

Three conditions can stimulate corrosion including moisture, metal surfaces and electron acceptors. Elimination of any of these conditions can stop the corrosion process. Metals can be protected by applying a negative charge or applying a coating or anodizing. One useful procedure is to coat the metal surface with paint or enamel, which provides a barrier between moisture and the metal. The coating does not allow direct contact with moisture and metal surfaces. The salt spray Test Chamber is used to check the electrical resistance performance of the surface coating. Due to its corrosion resistance properties, stainless steel is used exclusively in the automotive industry and the domestic sector. The chromium content of stainless steel exceeds 10.5%. Corrosion is an essential property required by manufacturers and suppliers using stainless steel . Stainless steel is used for accelerated corrosion testing in a salt spray chamber. This test procedure is one of the ancient procedures for checking the resistive properties of surface coatings . This test has many advantages and can examine a wide variety of materials.

How to protect metals from corrosion or how to identify the resistance of surface coatings to protect materials from corrosion?

These issues have significant implications for manufacturers of fasteners, springs or electronics. Industrial labs use good metals for surface coating (stainless steel preferred) to protect the metal from corrosion, but how long will the surface coating work on the metal? The answer to this question is the salt spray Test Chamber.

Salt spray Test Chambers are used to check the corrosion resistance of surface coatings and can predict the life cycle and durability of that particular coating. The test is solid and has many benefits:

• This test is valid and inexpensive compared to relative corrosion performance between competing systems.

• Any type of metal specimen can be tested in standard dimensions.

• The salt concentration acts as an electrolyte, and periodic sample checks are done to check for corrosion.

• The temperature is set between ambient and 45 degrees Celsius and the test program is optimized thanks to the see-through cover on top of the machine.

• This test calculates the number of years a surface coating will protect against corrosion.

Salt spray Test Chambers simulate actual environmental conditions and are widely used to evaluate new metal or paint coatings. The equipment can also be used for chemical treatment and paint treatment as well as for testing the resistance strength of metal coated steel sheet products.
