38. Electropolishing
Electropolishing is an electrochemical process similar to, but the
reverse of, electroplating. The electropolishing process smooths and
streamlines the microscopic surface of a metal object. As a result, the
surface of the metal is microscopically featureless, with not even the
smallest speck of a torn surface remaining.
The metal object to be electropolished is immersed in an
electrolyte and subjected to a direct electrical current. The object
is maintained anodic, with the cathodic connection being made to
a nearby metal conductor.
During electropolishing, the polarized surface film is
subjected to the combined effects of gassing (oxygen), which
occurs with electrochemical metal removal, saturation of the
surface with dissolved metal and the agitation and
temperature of the electrolyte.
Electropolishing selectively removes microscopic high points or
"peaks" faster than the rate of attack on the corresponding
micro-depressions or "valleys." Stock is removed as metallic salt.
Metal removal under certain circumstances is controllable and can
be held to 0.0001 to 0.0025 inch.
The basic metal surface is subsequently revealed — bright, clean
and microscopically smooth. By contrast, even a very fine
mechanically finished surface will continue to show smears and
other directionally oriented patterns or effects.

passivating.
39. Passivation
Pas.si.vate
.........To render a metal less susceptible to corrosion by coating the surface with
a substance, such as an oxide.
Passivation also is accomplished by Electropolishing.
Electropolishing is an electrochemical process that is a
SUPER PASSIVATOR of stainless steel
and
results in a more passive surface.
This is typically done to remove any "free-iron" from the surface of the metal,
which enhances the corrosion resistance of the stainless steel surface and
accelerates the re-formation of the passive layer.
*************************************************************
In years gone by, the process specified was to .............
"pickle and passivate" - a two step method - in order to
create a surface on stainless steel that would be resistant to
corrosion.
Passivation of stainless steel is done to make the surface more
passive and corrosion resistant.
The passivation of stainless steel is a process performed to make a surface
passive, i.e., a surface film is created that causes the surface to lose its chemical
reactivity. Stainless steel passivation unipotentializes the stainless steel with the
oxygen absorbed by the metal surface, creating a monomolecular oxide film.
Passivation can result in the very much-desired low corrosion rate of the metal.
The passivation of stainless steel is performed when free iron, oxide scale, rust, iron
particles, metal chips or other nonvolatile deposits are removed that adversely affect the
metallurgical or sanitary condition or stability of the surface.
40. What is Stainless Steel Passivation ?
Stainless passivation is the process by which stainless steel will spontaneously
form a chemically inactive surface when exposed to air or other oxygencontaining environments. Some important facts to know when considering
stainless steel passivation:
Steels containing more than 11% Chromium are capable of forming
an invisible, inert or passive, self-repairing oxide film on their
surface. It is this passive layer that gives stainless steels their
corrosion resistance.
If a stainless steel surface is scratched, then more Chromium is
exposed which reacts with oxygen allowing the passive layer to
reform. However, if a particle of carbon steel is embedded in the
scratch then the passive layer cannot reform and corrosion will
occur when the metal is wetted or exposed to a corrosive
environment.
Because during handling and processing such as rolling, forming, machining, pressing,
tumbling, and lapping, particles of iron or tool steel or abrasive particles may be embedded
in or smeared on or into the surfaces of stainless steel components. If allowed to remain,
these particles may corrode and produce rust spots on the stainless steel. This is due to the
formation of a galvanic couple between two dissimilar metals that can promote a corrosive
reaction. To dissolve the embedded or smeared iron and prevent this condition, as well as
restore the original corrosion-resistant surface, semi-finished or finished parts are given a
'passivation' treatment.
Passivation remains a critical step in maximizing the essential corrosion
resistance of parts and components machined from stainless steels. It can
make the difference between satisfactory performance and premature
failure. Incorrectly performed, passivation can actually induce corrosion.
41. Reasons for Passivating in Welding
– Increase corrosion resistance of fabricated parts.
– Removal of weld colouration.
– Restoration of protective oxide layer.
Contaminants are potential corrosion sites which, if not removed,
result in premature corrosion and ultimately result in deterioration
of the component.
• Especially in welded areas
Passivation is a post-fabrication method of maximizing the inherent corrosion resistance of the stainless
alloy from which the workpiece was produced. It is not a scale removal treatment, nor is it like a coat of paint.
There is no universal agreement on the precise mechanics of how passivation works. But it is certain that a
protective oxide film is present on the surface of passive stainless steel. This invisible film is considered to
be extremely thin, less than 0.0000001 inch thick, which is about 1/100,000 the thickness of a human hair!
A clean, freshly machined, polished or pickled stainless steel part automatically acquires this oxide film from
exposure to oxygen in the atmosphere. Under ideal conditions, this protective oxide film completely covers
all surfaces of the part.
During the machining process, a microscopic amount of free iron may be worn
off the cutting tool and transferred to the surface of the stainless steel
workpiece. Under certain conditions, a thin coating of rust may appear on the
part. This is actually corrosion of the steel from the tool and not the parent metal.
Sometimes the crevice at the embedded particle of steel from the cutting tool or
its corrosion products may cause an attack of the part itself.
Similarly, small particles of iron-containing shop dirt may adhere to the part surface.
Although the metal may appear shiny in the as-machined condition, the invisible
particles of free iron can lead to rusting on the surface after exposure to air.
Exposed sulphites also can be a problem. They come from the addition of sulfur to
stainless steels to improve machinability. Sulphites improve the alloy’s ability to form
chips that break away cleanly from the cutting tool during the machining process. Unless
the part is properly passivated, sulphites can act as initiation sites for corrosion on the
surface of the fabricated product.
