When an aluminum plate is bolted to a steel plate, what is required at the bolted joint to minimize bimetallic corrosion?
The plates should be bolted together in such a way as to ensure good electrical contact between the plates.
The plates should be electrically insulated from one another by use of non-conductive gaskets and non- conductive ferrule sleeves with the bolts.
Steel and aluminum are so close together on the Noble series that no particular provision need be made for bolting steel and aluminum plates together.
The plates should be bonded together electrically by joining the plates by a bonding strap in addition to bolting together.
