  2. Salt spray test - Wikipedia

    en.wikipedia.org/wiki/Salt_spray_test

    The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

  3. Cyclic corrosion testing - Wikipedia

    en.wikipedia.org/wiki/Cyclic_corrosion_testing

    Cyclic Corrosion Testing (CCT) has evolved in recent years, largely within the automotive industry, as a way of accelerating real-world corrosion failures, under laboratory controlled conditions. As the name implies, the test comprises different climates which are cycled automatically so the samples under test undergo the same sort of changing ...

  4. Magnetic particle inspection - Wikipedia

    en.wikipedia.org/wiki/Magnetic_particle_inspection

    There are several types of electrical currents used in magnetic particle inspection. For a proper current to be selected one needs to consider the part geometry, material, the type of discontinuity one is seeking, and how far the magnetic field needs to penetrate into the part.

  5. Kesternich test - Wikipedia

    en.wikipedia.org/wiki/Kesternich_test

    The Kesternich test is a common name for the corrosion test with sulfur dioxide (SO 2) under general moisture condensation. This test was developed in 1951 by Wilhelm Kesternich [1] to simulate the damaging effects of acid rain. Acid rain and acidic industrial pollutants are corrosive and can degrade coatings and plated surfaces. Kesternich ...

  6. Dye penetrant inspection - Wikipedia

    en.wikipedia.org/wiki/Dye_penetrant_inspection

    Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).

  7. Corrosion monitoring - Wikipedia

    en.wikipedia.org/wiki/Corrosion_monitoring

    Corrosion monitoring is the use of a corrator (corrosion meter) or set of methods [1] and equipment to provide offline or online information about corrosion rate expressed in mpy (mill per year). [ 2 ] - for better care and to take or improve preventive measures to combat and protect against corrosion .

  8. Slow strain rate testing - Wikipedia

    en.wikipedia.org/wiki/Slow_strain_rate_testing

    Slow strain rate testing (SSRT), also called constant extension rate tensile testing (CERT), is a popular test used by research scientists to study stress corrosion cracking. It involves a slow (compared to conventional tensile tests) dynamic strain applied at a constant extension rate in the environment of interest.

  9. Accelerated aging - Wikipedia

    en.wikipedia.org/wiki/Accelerated_aging

    Salt spray test, also known as salt fog testing, is a widely utilized method in environmental stress testing to assess the corrosion resistance of materials and surface coatings. By exposing specimens to a controlled saline environment, this accelerated aging test simulates the corrosive effects of marine and coastal conditions, providing ...
