Galvanic corrosion between ss and aluminum
WebStainless steel reacts with aluminum in a process called galvanic corrosion. This corrosion occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte, like salt water. When this happens, electricity flows between the two metals, causing corrosion. This article will walk you through galvanic corrosion ... WebIn some cases, aluminum and steel are used together. For example, the use of stainless steel screws in aluminum is common. However, this type of connection can create some problems due to galvanic corrosion. …

WebMar 16, 2024 · Corrosion potential and the galvanic series. When a metal corrodes in an electrolyte, atoms from the metal separate into ions and electrons (e - ), with the ions dissolving into the electrolyte. For example, for iron (Fe) the reaction is: Fe → Fe 2+ + 2e −. This is called an anodic reaction and Fe 2+ ions are formed.
