cyaniding - A hardening metal where the heated metal
is introduced to a cyanide bath. The metal absorbs
nitrogen and carbon from the cyanide and creates a
hardened surface.

cycle - A complete series of events or operations that
recur regularly. The series ends at the same condition
as it started so that the next series of events can
immediately take place.
cycle - A period of time during which a sequence of
recurring events is completed. In aviation, a cycle can
be one takeoff and one landing, -. one extension and
retraction of the flaps, one retraction and extension of
the landing gear, etc.
