Dil:

Immersion corrosion testing is used to evaluate the corrosion performance of metallic materials under long-term exposure to specific aqueous environments. The method involves exposing samples to controlled electrolyte solutions to simulate service conditions and assess general corrosion behavior, weight loss, and surface degradation over time.

 Testing can be performed in accordance with relevant ASTM standards to determine corrosion rate, material stability, and environmental compatibility in applications such as marine, oil and gas, and industrial process environments.
