High sample quality and reproducible results can only be achieved with high quality consumables. Selecting the right consumables for each specific application is not just a matter of preparation quality - it is also the best way to save time and money.
METKON® cutting, grinding, mounting and polishing consumables for microstructural analysis are produced to match to your specific requirements for high preparation quality. Chosen from a wide selection, designed and tested for use on METKON® metallographic equipment as well as on competitive units.
   
Cutting
Sample preparation starts with cutting and good cutting means a good start. Selecting the right cut-off wheel ensures freedom from burn and distortion and is the best way to save time and consumables. Correct cutting produce specimens which are in perfect condition for the next preparation steps.

Abrasive Cutting:
The most commonly used abrasives for the cutting of different materials are Si C and Al2 O3.

Silicon carbide is suitable for non-ferrous metals whereas Aluminium Oxide is preferred for ferrous metals. Hard wheels are used for cutting soft materials while soft wheels are recommended for cutting harder materials. All METKON® cut-off wheels have an arbor diameter of 32mm.

Diamond Cutting:
METKON® diamond cut-off wheels are available in resin bond as well as in metal (bronze) bond.

Metal bonded wheels are used for cutting brittle materials, such as ceramics or minerals, while resin bonded wheels are used for more ductile materials, such as sintered carbides or composites containing hard phases.

Mounting
After cutting the specimen the next step is mounting. The aim of mounting is to protect fragile materials, thin layers or coatings during perparation as well as to provide good edge retention. Mounting produces specimens with uniform size so that it is easier to handle in automatic holders for future preparation steps.

The most important properties of a mounting compound are; Hardness, Shrinkage and Viscosity.

The hardness of the compound should match the hardness of the specimen in order to avoid uneven abrasion during grinding. If the shrinkage during curing is large, a gap between the specimen and the mount will occur and edge will not be adequately protected. Viscosity is important to reach to all areas.

Two different types of hot mounting media are available; Thermosetting and Thermoplastic. Thermosetting compounds harden under combined heat and pressure and can be taken out of the mould at elevated temperature. Thermoplastic compounds do not require high pressure either for melting or curing. However, cooling nearly to room temperature is necessary. Due to low mounting pressure required, thermoplastic are widely used to mount fragile and sensitive specimens.

Mechanical Preparation
Grinding:

In order to obtain scratchfree surfaces without deformation, successive material removals by abrasives is necessary. Grinding is the next stage after sectioning. Grinding is divided into two processes: Coarse grinding and Fine grinding.

The purpose of coarse grinding is to obtain a level surface and to remove scale, burrs or surface irregulation from the specimen. Fine grinding removes the deformation resulting from coarse grinding to make the surface ready for polishing which is the final stage.

Polishing:

After grinding, the quality of surface finish is not adequate for microscopic analysis. Therefore, it is essential to improve the surface quality by polishing. Different polishing clothes are used for different applications. Alumina and Diamond compounds are used as polishing agents. Alumina powders and suspensions are available from 0.05 to 1 micron whereas diamond pastes have particles sizes from 0.25 to 15 microns.
