Galvanic corrosion chart metals
Advisory - Allied Scientific Pro
The rate of corrosion of a galvanic couple is a function of the difference between the reactivity of the metals. The galvanic series for metals with salt water as the electrolyte is outlined in Table 2-3. The farther apart two metals are on the galvanic series chart, the faster the active (anode) metal will corrode in the presence of the ...

Corrosion: Corrosion of metals can be a major problem, especially for long-term structural applications like cars, bridges, and ships. Most corrosion is electrochemical (galvanic) in nature. To have corrosion, an anode (a more easily oxidized region) and a cathode (a less easily oxidized region) must be present.

3 The materials of, for example, screws and nuts that are made up of a few materials can be listed in the DMPL. The materials (metals and plastics) of complex parts can be listed in the DML with, for example, outgassing, toxicity, flammability, corrosion and stress corrosion values and reference to the DMPL item.

The first type of corrosion to consider is galvanic – this means that dissimilar metals when immersed in water generate a small potential difference which quickly corrodes the metals involved. Metals and alloys present in cell phones include tin solder, brass, nickel, copper, gold, palladium and a …

Galvanic Corrosion: The corrosion of one of two dissimilar metals is referred to as galvanic corrosion, or dissimilar metal corrosion, and uses the property of electrolysis to diminish the weaker of the two metals. The weaker metal, or anode, has a lower number on the galvanic table in relation to the second metal, the cathode.

Electrical/dissimilar metal (galvanic) corrosion: In the presence of an electrolyte such as salt water, electrolytic corrosion of aluminum can. Aluminum is quite susceptible to this corrosion type, so much so that it is commonly used as a sacrificial electrode in galvanic environments to protect other parts (the aluminum becomes the path of ...
