To minimize galvanic corrosion, select fasteners based on their material compatibility with the substrates. The closer together the material are on the chart to the right, the less galvanic action will occur. Metals listed on the top of the chart (anodic) will corrode faster than the metals on the bottom of the chart (cathodic).
This chart is designed to assist in broadly assessing the risk of galvanic corrosion associated with a given metal coming into contact with another metal. To use the chart, align the metal to be assessed (for the risk of corrosion) in the left column with the Contact
Galvanic and Corrosion Compatibility Dissimilar Metal Corrosion
There are three conditions that must exist for galvanic corrosion to occur. First there must be two electrochemically dissimilar metals present. Second, there must be an electrically conductive path between the two metals. And third, there must be a conductive path for the metal ions to move from the more anodic metal to the more cathodic metal.
To minimize galvanic corrosion, fasteners should be considered based on their material compatibility with the substrates. Determine the materials being fastened and choose a fastener
Understanding Galvanic Corrosion: Concepts, Causes, and …
2024年2月14日 · Galvanic Corrosion Chart Usage Instructions. Identify Metals: Locate the two metals you are interested in from the chart. Compare Positions: Note their positions on the galvanic series. Determine Potential Difference: The metal higher up (more anodic) is at risk of corrosion when in electrical contact with the metal lower down (more cathodic).
Galvanic Corrosion - PEM® Fastening Products
Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list.
Galvanic Corrosion: A Guide for Architects (with a Galvanic Series Chart)
2024年8月9日 · If you're an architect designing a metal exterior, you've probably heard of galvanic corrosion. Most designers know enough to be dangerous, but how exactly does galvanic corrosion work, and what are the best practices for preventing it? View our galvanic series chart, pictures, definitions, and even a mnemonic device!

Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list.
assessed, relative to the potential for galvanic corrosion, with the use of charts depicting the galvanic (or electromotive force) series in different environments. The galvanic series indicates which dissimilar metal will tend to corrode (anode) and which dissimilar metal will tend to support the reduction reaction
