| Electropolish |
(No mil spec)
The electropolish process is the removal
of substrate (base) material in such a fashion as to impart a highly reflective
surface in most cases; diminishing scratches, burrs and unwanted sharp
edges from most metals. Electropolishing is most frequently used on stainless
steel, relatively high in both nickel and chromium content (300 and 400
series). Finishes from satin to mirror bright are produced by controlling
time, temperature, current, bath make-up or singularly or in combinations.
Surface appearance results are also dependent on pre-process condition.
Typical material removal .0002" per surface, unless otherwise specified.
Processing of close tolerance surfaces requires a significant amount of
vigilance from the plater: there is no undoing the results. As an adjunct,
the electropolish process creates a super-passivated surface of the base
metal, maximizing the corrosion resistant properties of the particular
alloy.
Applications:
Medical components; food processing
machinery; pharmaceutical filling devices; complex stainless details; computer
peripheral parts; aerospace technologies. More
