Description

Technical field [0001] The invention relates to the field of corrosion electrochemistry, and more specifically to a dynamic corrosion test device for multi-factor synergy. Background technique [0002] Covering a complete and dense corrosion product film has the effect of slowing down corrosion and protecting the base metal. However, in actual use, the corrosion product film on the surface of the base metal is often affected by abrasion, and it is easy to thin or even break, causing the base metal to corrode. Enlargement, such as freight cars, bridge decks, ship boards, pipe inner walls, etc. Due to the complexity of the real corrosion environment, it is difficult to conduct real-time testing in the field. Therefore, it is particularly important to design and manufacture a dynamic corrosion test device that can be close to the real service environment of the material. At present, the design of the dynamic corrosion experiment device mainly focuses on the two factors of temperatu...
