The cyclic immersion test chamber, also known as a cyclic immersion corrosion test chamber, is an apparatus designed to simulate the corrosion behaviour of materials under specific environmental conditions. Primarily employed to determine the weathering and corrosion resistance of metals subjected to cyclic immersion testing in salt solutions, with or without applied stress, it is particularly suited for quality control during the manufacturing of metals, including aluminium alloys and steel materials, as well as for evaluation during alloy development. Depending on the chemical composition of the test solution, this procedure can replicate the corrosive effects encountered in seawater splash zones, de-icing fluids, and acidic salt environments. Cyclic immersion testing is applicable to metals and their alloys, metallic coatings, conversion coatings, anodised coatings, and organic coatings on metal surfaces. It involves immersing the specimen in a specific liquid, removing it for drying, then re-immersing it in the liquid, followed by removal and drying... Following this cyclical operation, the specimens are removed for observation and evaluation to study material corrosion resistance in specific environments. This method is suitable for accelerated artificial weathering corrosion testing of weathering steels used in railways, bridges, building materials, steel, and aluminium alloy industries. Suitable for small specimens undergoing cyclic immersion testing, this product simulates natural atmospheric corrosion conditions outdoors. By conducting accelerated artificial climate corrosion tests on weathering steel and its welding materials, it evaluates their quality performance against outdoor atmospheric corrosion. It is suitable for immersion corrosion testing of product samples in various research institutions, factory laboratories, and sectors including aviation, aerospace, machinery, and electronics.
