Recognizing that titanium is highly susceptible
to hydrogen pickup or embrittlement,
metallurgical engineers at General Magnaplate
created a series of coating processes that would
preclude any hydrogen absorption. Called
CANADIZE, these "synergistic" coatings
were used to prevent galling at the joints and
in the drive shaft of titanium core-sample drill
tubes used in NASA's exploration of the moon.
The coatings also prevented contamination of
moon rock samples by titanium or other foreign
materials.
The CANADIZE process begins with a
proprietary cleaning process. The part is then
enhanced to the desired thickness in a
proprietary solution.
Through predetermined time and current
control, a hard ceramic surface is formed. In
instances where permanent dry lubrication is
desired, one or more carefully selected
engineering materials are infused into the
surface, i.e. fluorocarbons, polymers,
molybdenum disulfides, graphites, or
combinations of these well known dry lubricants.
Its lubricity reduces surface friction
significantly, allowing the free flow of liquids
while resisting the adhesion of contaminates
over a broad temperature range.
CANADIZE coating thickness range can be
provided from 0.0001" to 0.0005".
Precise control of the coating thickness permits
use on machine threads and similar
close-tolerance parts. Titanium 6AL 4V produces
the best ceramic coating - other alloys will not
permit more than a thin film. Color can be
produced in the lower thickness range. General
Magnaplate's engineers are available for
consultation regarding optimum thickness
recommendations.
