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.

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.

http://www.delstar.com/electropolishing.html

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 oxygen-

containing 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.

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.
