Harvey process
name
A
process
for
hardening
the
face
of
steel,
involving
the
additional
carburizing
of
the
face
of
a
piece
of
low-carbon
steel
by
heaping
a
solid
carbon-rich
fuel
(such
as
charcoal)
on
the
face
of
the
steel
and
then
subjecting
this
to
very
high
heat
at
high
pressure
for
a
prolonged
period
of
time,
followed
by
a
violent
chilling,
as
by
a
spray
of
cold
water.
This
results
in
a
thick
surface
of
extreme
hardness
supported
by
material
gradually
decreasing
in
hardness
to
the

steel
at
the
back.

A process for hardening the face of steel, involving the additional carburizing of the face of a piece of low-carbon steel by heaping a solid carbon-rich fuel (such as charcoal) on the face of the steel and then subjecting this to very high heat at high pressure for a prolonged period of time, followed by a violent chilling, as by a spray of cold water. This results in a thick surface of extreme hardness supported by material gradually decreasing in hardness to the unaltered soft steel at the back.
Harvey process is a name for a process used to harden the face of steel.
