Case Hardening

Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question has been formed into its final shape, but can also be done to increase the hardening element content of bars to be used in a pattern welding or similar process. The term face hardening is also used to describe this technique, when discussing modern armour.

Famous quotes containing the words hardening and/or case:

    With sixty staring me in the face, I have developed inflammation of the sentence structure and definite hardening of the paragraphs.
    James Thurber (1894–1961)

    Television is an excellent system when one has nothing to lose, as is the case with a nomadic and rootless country like the United States, but in Europe the affect of television is that of a bulldozer which reduces culture to the lowest possible denominator.
    Marc Fumaroli (b. 1932)
