Definition - What does Corrosion Testing mean?
Corrosion testing refers to the processes conducted by laboratories in order to solve, prevent or mitigate problems related to corrosion. These processes can be applied in industrial materials and infrastructure products, and are often used in failure analysis.
All corrosion laboratories are composed of expert failure analysts, chemists and engineers that are all certified in corrosion testing. Such tests can provide useful information in order to make sound decisions regarding selection of materials, processing and treatment.
Corrosionpedia explains Corrosion Testing
Corrosion laboratories can conduct a broad range of laboratory tests that are typically focused on areas such as:
- Heat transfer
Testing of various materials used in industrial applications is required to verify conformation to quality standards. One example is immersion testing, which is considered the most popular and simplest type of corrosion test. This test is used to assess different materials that are subjected to particular conditions. It is a very versatile process which can be personalized to meet specific needs regardless of application. In this test, the testing apparatus can expose the specimen to test solutions and then subject it to different physical or metallurgical situations, such as crevices and heat treatment.
Another test is the hot wall test, which is utilized to evaluate situations where metal vessels are hotter than bulk solutions. These are common in external heated vessels where corrosion is typically impacted by temperature. In this test, elevated temperatures signify high levels of corrosion activity.
There is also a test known as salt spray. This technique is used to evaluate a coated sample's resistance to corrosion. This test produces an attack to coated specimens to measure suitability as a protective coating.
In addition to these, there are numerous other corrosion testing techniques available that help prevent loss due to corrosion.
