CEMENTATION
Cem`en*ta"tion, n.
1. The act or process of cementing.
2. (Chem.)
Definition: A process which consists in surrounding a solid body with the
powder of other substances, and heating the whole to a degree not
sufficient to cause fusion, the physical properties of the body being
changed by chemical combination with powder; thus iron becomes steel
by cementation with charcoal, and green glass becomes porcelain by
cementation with sand.
