Chrome

Chrome or Chromium is a chemical element which has the symbol Cr.

It is a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point.

It is also odorless, tasteless, and malleable.

The name of the element is derived from the Greek word “chrōma” (χρώμα), meaning colour,because many of its compounds are intensely coloured.

Chromium oxide was used by the Chinese in the Qin dynasty over 2,000 years ago to coat weapons such as bronze crossbow bolts and steel swords found at the Terracotta Army.

It later came to the attention of the west when it was discovered by Louis Nicolas Vauquelin in the mineral crocoite in 1797.

Crocoite was used as a pigment, and after the discovery that the mineral chromite also contains chromium, this mineral was used to produce pigments as well.

Chromium was regarded with great interest because of its high corrosion resistance and hardness.

A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding chromium to form stainless steel.

This application, along with chrome plating (electroplating) are currently the highest-volume uses of the metal.

The relative high hardness and corrosion resistance of unalloyed chromium makes it a good surface coating, being still the most “popular” metal coating with unparalleled combined durability.

A thin layer of chromium is deposited on pretreated metallic surfaces by electroplating techniques.

There are two deposition methods: Thin, below 1 µm thickness, layers are deposited by chrome plating, and are used for decorative surfaces.

If wear-resistant surfaces are needed then thicker chromium layers are deposited.

Chromium is used alot on the automotive trade because of its super shiny mirror finish, which give a very professional and quailty look
