What is Corrosion Testing? - Definition from Corrosionpedia
Some test samples and procedures are designed to assess specific kinds of corrosion, such as crevice corrosion, stress-corrosion cracking, and erosion corrosion. The atmospheric corrosion of coated samples can be examined by salt spray or fog testing. Here, a 5% NaCl solution is atomized in a chamber at a … See more One of the most common and simplest methods in laboratory tests is the immersion test. In this kind of test, whose procedure is clarified by ASTM and NACE, the weights of dried … See more Some visual examination is also suggested to evaluate localized corrosion like pitting or exfoliation. Furthermore, optical or scanning electron microscopes; elemental and compositional analyses such as energy … See more Electrochemical tests are the other category of laboratory tests that can provide valuable information about corrosion electrochemical reactions and the mechanisms … See more In another atmospheric method called the weathering test, the durability of organic, paint-coated samples is examined by exposing them to UV light and cyclic cooling-heating … See more WebApr 12, 2024 · Here, potential metallic bipolar plate (BP) materials were manufactured by laser coating NiCr-based alloys with different Ti additions on low carbon steel substrates.
