Who discovered chromium?
As to how chromium was discovered, that may be lost in history. Some of the tips of bronze spears of the Terra cotta Army, ~300 BCE, show no corrosion, and have been found to be coated with a chromium compound. That has to be a long-lasting coating! Chromium is so named because many of its compounds are brightly coloured. Chroma = colour in Greek. Some chromium salts are quite toxic, and are part of the story line of the film Erin Brokovich. This concerns the hexavalent form. In modern times, it was first identified by Voiquelin around 1797. Probably in the analysis of a bright red lead chromate.

How does coating with another metal prevent corrosion?
when you coat a metal in another metal you are protecting the inside metal. The metal metal that is being used as a coat must be more corrosive than the 1st metal. For example iron can be coated in zinc because zinc is more corrosive than iron. This is common on a ship, the iron hull is coated with blocks of zinc which will act as a barrier and will corrode instead of the iron. The zinc blocks must be renewed after a period of time however. Other ways of stopping metals from corroding include, chromium plating, coating in paint, oil or plastic.
