Luigi Galvani lends his name to a process of coating iron or steel with what metal?

Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten zinc.

The earliest known example of galvanized iron was encountered by Europeans on 17th-century Indian armor in the Royal Armouries Museum collection. It was named in English via French from the name of Italian scientist Luigi Galvani. Originally in the 19th century, the term "galvanizing" was used to describe the administration of electric shocks; this was also called Faradism. This usage is the origin of the metaphorical use of the verb "galvanize", such as to "galvanize into action" meaning stimulating a complacent person or group to take action.
