Three conditions can stimulate the corrosion including moisture, metallic surface and an electron acceptor. Removing any one of these conditions can stop the corrosion process. Metals can be protected by applying a negative charge or applying a coating or anodizing. One of the useful procedure is coating a metal surface with paint or enamel providing a barrier between moisture and metal. The coating disallows direct contact with humidity and metal surface. The salt fog cabinets are used to check the resistance properties of the surface coatings.
The stainless steel is used specifically for the automotive industries and domestic sectors due to its corrosion resistance property. Stainless steel has chromium content more than 10.5 percent. Corrosion is an essential property which is required by the manufacturers and suppliers who use stainless steel. Stainless steel is used for performing accelerated corrosion test in Salt Fog Cabinets. The test procedure is one of the oldest processes to check the resistance property of surface coating. The test has many advantages and can check the multi-materials.
How to save the metal from corrosion or how to identify the resistance of surface coating to protect the material from corrosion? These questions are significant for the manufacturers of fasteners, spring or electronic goods. The industrial labs use best metals for surface coating (preferred stainless steel) to protect the metals from corrosion but how long the surface coating is going to work on the metal? The answer to this question is salt fog cabinets.
Benefits of Salt Fog Cabinets
The salt fog cabinets are used to check the corrosive resistance property of surface coatings and can predict the life cycle and durability of that specific coating. The test is reliable and has many benefits:
The salt fog cabinets are the best lab testing equipment as it simulates the actual environmental conditions and are used extensively in the evaluation of new metallic or paint coatings. The device is also useful for chemical treatments and paint treatments as well as to test the resistance strength of metallic coated steel sheet products.
