WebMay 3, 1995 · One of the key factors in the reaction between dissimilar metals is the contact surface area. A severe reaction can occur when a large cathode (higher or more positive … WebIn general, aluminum is a more anodic metal than steel, meaning it is more likely to corrode and be attacked by the environment. When these two metals come into contact, they create an electrical potential difference that can cause galvanic corrosion. This corrosion is accelerated by high moisture levels and salt and acid exposure.
WebGalvanic corrosion occurs when two dissimilar metals are in contact electrically in the presence of an electrolyte. During this process, corrosion occurs on the anode, whereas the cathode is protected. For example … WebSep 1, 2024 · The reason for the confusion if galvanic corrosion happens or not between aluminum and steel is that stainless steel can be found as passive or active, and if the …
