Metallographic Polishing Pads with Adhesive Information



Polishing Cloths

Polishing is the most important step in preparing a specimen for microstructural analysis. It is the step which is required to completely eliminate previous damage. Ideally the amount of damage produced during cutting and grinding was minimized through proper blade and abrasive grinding so that polishing can be minimized.

Metallographic Polishing Pads

Cloths for polishing vary by the height of their fiber, known as the nap and by the stiffness or resiliency of the fiber. In general, the lower nap (also non-woven) and stiffer fiber cloths are used for the rough polishing steps. These types of polishing cloths or pads are very effective in removing sectioning damage done by cutting and coarse grinding. Conversely, higher napped polishing cloths provide a more gentle abrasive interaction for the final polish. The Polishing Pads are available with either a pressure sensitive adhesive (PSA) or on a magnetic backing. The following is a list of most common polishing cloths:

Polishing Pad Selection Guidelines

Metallographic metal mesh cloth

CERMESH Metal Mesh cloth - this is a wire mesh material useful for coarse and intermediate lapping/polishing. The texture of this wire allows for the abrasive to become semi-fixed; thus offering the advantage of increased stock removal, while minimizing damage Metallographic CERMESH metal cloth
Metallographic POLYPAD polishing pad

POLYPAD Polishing Pad - this cloth is a synthetic polyester polishing pad which has a similar action to a nylon pad, with the exception that it is much more durable. It is used in the intermediate polishing steps Metallographic POLYPAD polishing cloth
Metallographic TEXPAN Polishing Cloth

TEXPAN Polishing Pad - this is the most commonly used polishing cloth material for the intermediate polishing steps. TEXPAN Polishing pad is a non-woven polishing pad. Metallographic TEXPAN polishing cloth
Metallographic Black Chem 2 Polishing Pad

Black CHEM 2 Polishing Pad this is a porometric polymer pad which has a consistency similar to a rubber type of pad. Black CHEM 2 pad has a low nap but behaves as an intemediate polishing pad with a performance between low napped and high napped pads. Metallographic Black Chem polishing pad
Metallographic Dacron Polishing Pad

DACRON II Polishing Cloth - this is a low napped polishing pad for polishing primarily with 1-15 micron diamond abrasives. The DACRON II pad is the most popular intermediate polishing pad in Europe and is used mostly for polishing metals. Its high nap provides it a very soft and gentle polishing action.
Note: DACRON is a registered trade name of DUPONT Corporation.

Metallographic Nypad polishing pad

NYPAD Polishing Pad - this is a low napped silk polishing pad for intermediate polishing primarily with intermediate diamond abrasives. Metallographic Nypad polishing pad
Metallographic Gold Pad polishing pad

GOLD PAD Polishing Pad is a low napped polishing pad for imtermediate polishing primarily with 1-9 micron diamond. Metallographic Gold Pad polishing pad
Metallographic Atlantis polishing pad

ATLANTIS Polishing Pad - is a woven low napped final with a foam backing for better matting to the specimen sample. It is an excellent polishing pad for 1-6 micron diamond. Metallographic Atlantis polishing pad
Metallographic MICROPAD polishing pad

MICROPAD Polishing Cloth- this is the most common high napped final polishing pad for most metals and polymers. Its high nap provides it a very soft and gentle polishing action. Metallographic MICROPAD polishing pad
Metallographic TRICOTE polishing pad

TRICOTE Polishing Pad- a tight high napped final polishing pad for most metals. It has a tigher nap then the MCIROPAD Polishing Pads Metallographic TRICOTE polishing pad
Metallographic NAPPAD polishing pad

NAPPAD Polishing Pad- this is another high napped final polishing pad useful for most metals and polymers. It has a higher nap than MICROPAD, providing it with a very gentle polishing action which is very useful for polishing soft materials such as copper, aluminun and austentite steels. Metallographic NAPPAD polishing pad
Metallographic Moltec Polishing pad

MOLTEC 2 Polishing Pad - this is wool polishing cloth used for final polishing and has a very high nap. It is most commonly used for final polishing metals where edge retention is a minimal consideration. Metallographic MOLTEC polishing pad

Metallographic Moltec Polishing pad
FELT PAD Polishing Pad - this is thick felt pad used for final polishing glass and large surface area parts. Metallographic FELTPAD polishing pad

Polishing Process Description

Polishing can be broken into two stages: rough and final polishing. Proper rough polishing removes all subsurface damage produced during cutting and grinding. In most cases this is accomplished with polycrystalline diamond abrasives and low napped polishing cloths. The final polishing step should be kept to a minimum and used only to clean up surface blemishes. Note that excessive final polishing times can result in phase relief, edge rounding, smeared material and inclusion pull-out. Final polishing is accomplished with high napped cloths and fine graded alumina or colloidal silica abrasives.

Minimizing Polishing Artifacts

To minimize polishing artifacts such as edge rounding, phase relief, smeared metal, grain pull-out and inclusion pull-out, the polishing time needs to be kept to a minimum. This can be accomplished by:

Minimizing sectioning damage and using the correct grinding abrasives are fairly obvious. However, using a flat supporting plate is generally over looked by most suppliers of metallographic equipment, and if they do consider plate flatness they generally do not go far enough. As a guideline, an 8-inch plate should have no more than a 0.0001 inch (2.5 um) runout, which represents a 0.6 um runout over a 1-inch diameter specimen. Recognize that final polishing abrasives have a typical size of 0.05-0.06 um, thus these tolerances are required to minimize polishing times. In addition, if the specimen is not flat on the polishing plate then a differential pressure occurs across the specimen, which causes polishing relief. Likewise for a 12-inch diameter plate the runout should not exceed 0.0002 inches (5 um). As a result both polishing times and differential polishing pressures can be minimized.

Suggestion: If your polishing plate is not flat within these tolerances they should be lapped to these tighter tolerances.

Trouble Shooting for Polishing

Symptom Cause Action
Coarse scratching -Contamination on polishing pad -Replace with a new pad
Tearing of pad -Too high a polishing force
-Improper lubrication
-Reduce polishing force
-Dispense lubricant or abrasive more frequently
Excessive relief or edge rounding -Improper polishi
-Excessive polishing times
-Refer to polishing cloth guide
-Reduce polishing times and re-examine effectiveness of previous step
