Lovatt's Sheradize specialty treatment for steel
improves hardness in heat-treated steels and is currently being applied
to all steels and cast iron. The Sheradize treatment is a unique process
which cannot be compared to any other steel treatment. The treatment uses
unique circuitry and a proprietary cold electrolyte which creates a molecular
structural change. The new surface causes no dimensional change, the treatment
is all penetration. There is no warpage since the treatment is done at
sub freezing temperatures. Change in color after treatment is very slight
from the original metal, in most alloys. Also, certain alloys of Sheradized
steel have proven extremely resistant to corrosive attacks by sea water.
The U.S. Navy has used both Sheradized steel and Akadized aluminum parts.
On the Rockwell C scale. Non heat treated steel generally
increase 4-6 points. Heat treated steel generally increases 10-20 points.
Sheradize provides a method by which one can normalize or stress relieve
a part after machining, grinding or welding and be assured of absolutely
Density of the molecular structure near the surface of the treated part
Offers good corrosion resistance to some steels. Significant improvement
has been reported for treated versus untreated parts.
The surface RMS of the treated part is normally improved by up to 50%
increasing lubricity characteristics, while providing a tough and durable
The Sheradize treatment removes gaseous interstitial impurities from the
treated area. Fatigue life of the component may be greatly improved through
the removal of residual stresses.
The life of cutting tools normally is extended many times over untreated
parts, or in some cases made it possible to cut with tools that prior
to treatment would not even make a minor cut in soft aluminum stock. After
the treatment there is significant increase in resistance to galling.
