How Does Coating Help To Protect Metals From Corrosion

Major Properties That Initiates Corrosion

Corrosion is the major problem that occurs on metal due to different environmental conditions. The three conditions that initiate corrosion includes metal surface, moisture and an electron acceptor. These are the prime factors due to the amalgamation of which corrosion initiates. By removing any of the factors from the mentioned three can helps to stop the process of corrosion.

How can metals be protected from corrosion?

Metals can be protected by applying a negative charge or by applying a coat or anodizing. One of the useful procedure which helps to protect the metals from corrosion is Coating. The coating helps to eradicate the direct contact of metals with humidity. Therefore, its is essential for the manufacturers in metal industries to coat or paint the metals with high-quality of paints so that premium quality of material with long working  life can be delivered to the customers.

How do the coatings get corroded?

But on the other hand, the coating and paints also get corroded after a period of time when they continuously remain in contact with humidity, moisture or other wet working conditions Hence, high-quality corrosion resistant coatings and metals are required. To test the quality and corrosion resistance strength of the metals, high-quality corrosion test chambers are utilized by the manufacturers of paint and metal industries. These chambers help to check the resistant properties of the paints, coating and metals.

Best Substrate used for Coating to Remove Corrosion?

The stainless steel material is widely used in automotive industries and in domestic sectors due to the corrosion resistant properties of the metals. Stainless steels contain more than 10.5 percent of chromium content in it. Corrosion resistance strength is an essential property which is required by the manufacturers and suppliers to test before using S.S. materials or metal sheets. The corrosion test chambers are used to perform accelerated corrosion test in Salt Fog Cabinets. The test procedure is one of the oldest processes which is used to check the resistance properties of the surface coatings. The test has numerous advantages and helps to test multiple materials.

How to identify the resistance of surface coatings corrosion?

The questions are significant especially for the manufacturers of spring, fasteners or electronic goods. The researchers and technicians of industrial laboratories make use of high-quality of metals such as stainless steel for the surface coating to protect the quality of final products from corrosion. But now the question arises that how long the coating will survive in wet working or humid environmental conditions on the substrate? This can be tested by making use of salt fog chambers to ascertain the actual working life of the products.

Key Benefits of Corrosion Test Chambers

The corrosion test chambers or salt spray chambers are used to test the corrosion resistance properties of the metals and coated surfaces and helps to predict the durability and life cycle of that specific coating. It is a reliable test method and offers several benefits to the manufacturers of metals and coatings.

  • It is an effective and affordable test method as compared to other corrosion resistance test performances between competing systems.
  • Any type of metal samples that can be tested in the chambers irrespective of the size and shape.
  • The salt concentration which is provided to create salt fog environment in the chambers acts as an electrolyte and inspection is performed at regular intervals to check the properties of corrosion.
  • The temperature can be set up to 45 degree Celsius, and test procedure can be examined due to the transparent Plexiglas material cover which is provided on the top of the machine.
  • The test helps to determine the number of years the surface coating will survive to protect the quality of the products against corrosion.

With so much of benefits, Salt Fog Cabinets are considered as the best lab testing machine as it creates actual environmental conditions inside the testing laboratories and helps to evaluate the actual working life of the metals, paints and coatings. The device is also used for paint treatments, chemical treatments and tests the resistance strength of metallic sheets that are duly coated with paints or coatings.

Salt Fog Chambers by Presto

Presto Stantest offers a wide range of corrosion test chambers that complies with internationals standards such as ASTM, ISO, BIS and many more. These are highly sophisticated chambers that are designed keeping in mind the testing requirements of different users for different test applications. The test equipment is fitted with glass wool insulation that ensures reliable and accurate test results. The air pressure inside the chamber is created using air flow meter to create an even temperature throughout the chamber. The rate of air pressure lies between 0 to 30 psi. The chamber is covered with the air jacket heating system that creates an even temperature throughout the test procedure. It is a widely used test machine which is used in testing laboratories for doing comparison testing. It offers direct visual observation of sample is possible on the cover.

Applications of Corrosion Test Chambers

Corrosion Test Chamber is an effective testing machine which is used in a large number of industries all across the globe such as Automotive Components, aircraft, industrial sector, military equipment.
