The popular diecasting family of alloys--aluminum, magnesium and zinc--are all "active" metals and potentially subject to problems, which is why galvanic corrosion
cannot be overlooked.

Approach to Investigating Chromate effects on Aluminum Alloy 2024-T3.
occurs where dissimilar metals are lapped over one another, where screws or bolts of one metal are used to fasten sheets of another metal together (see Figure 2) and where parts made of one metal are attached to another metal.
Several clinical cases of galvanic corrosion
have been reported in the literature.
A chemical reaction called galvanic corrosion
occurs between some dissimilar metals, and copper seems to be a leading culprit.
2]  reveal that corrosion resistance of composites are lower than matrix alloys, owing to galvanic corrosion
between the reinforcement and matrix alloy.
Made of high-grade PVC, Certa-Lok Well Casing is immune to electrolytic and galvanic corrosion
, and will not rust or rot like metal pipe.
This new powder coating line includes nylon 11 coating, which also prevents galvanic corrosion
between dissimilar materials.
Due to the galvanic corrosion
properties of zinc and stainless steel, the staff placed Teflon pieces between any spots where the two materials would come into contact, particularly at the bolt holes that connected the two segments of the statue.
Appropriate material selection to avoid galvanic corrosion
In addition it is hydrolysis resistant and can be used in environments where hot water leads to either seal attack or galvanic corrosion
of the metalwork.
Today, Magnaplate-applied coatings are used not only in space, but for such down-to-earth applications as the prevention of abrasion, erosion and galvanic corrosion
of plastic molds; the protection of the huge boring machines used in digging the England/France "Chunnel" from salt water corrosion; the permanent lubricating and hardening of high-speed machinery's aluminum guide surfaces; the solder-spatter-rejection on double wall copper tubing machines; and a host of other applications.
