mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
what the was on tooth hardening day?
Arteriosclerosis is hardening of the arteries.
Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.
Sclero means a hardening from the greek word "skleros". Sclerosis means a hardening of the skin.
Glomerulosclerosis means hardening of the glomerulus.
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.
Core hardening refers to the innermost portion of metal. When the outer layer remains soft, but the inner portion is hardened, this is core hardening.
No hydrogenating is the absorption of water, hardening is the process of something getting harder.
To increase the melting point of aluminium, (and treating this as a philosophical question), then hardening the 'crystal matrix' may be one approach. Surface hardening by work hardening, or perhaps by inserting nitrogen ions into the surface as is used in metal(ferrous) hardening.
