WebAug 31, 2024 · Graphite is by far the most noble in the galvanic series and will cause galvanic corrosion it with any material it is couples with. Graphite is excellent for hot, non-conductive fluids. Not so much for anything else. PTFE is ok, it's non conductive. It's biggest weakness is creep. WebGalvanic corrosion is a local form of corrosion. It is limited to the contact zone. The intensity of corrosion decreases rapidly with increasing distance, even by a few centimetres, from the point of contact between the two metals. This decrease is greater when the electrolyte is a poor conductor.
WebAnodic Index: Highly noble materials with “passive surfaces” are not as susceptible to galvanic corrosion as less noble materials or as noble materials with “active surfaces.” In this chart, magnesium is the least noble material, and graphite is the most noble material.
