Preparation Instructions – Metallography Non-binding recommendations for sample preparation Sample preparation The preparation of metallographic samples has the objective of providing the true structure for the qualitative and quantitative analysis. Increasingly fine layers of material are removed in a succession of work operations.
Metallographic Polycrystalline Diamond
Additional dispensing is generally dripped onto the surface at a rate of 1-2 drops every 10-15 seconds depending upon the polishing speed and surface area of the samples For mineral and ceramic specimen preparation it is recommended that diamond and colloidal silica (SIAMAT colloidal silica) be alternately dispensed.

The preparation of metallographic samples requires a precision cutting off in a wide variety of materials. A good lubrication is necessary to cool the cutting wheel and prevent the burning of the parts. In addition, the environment of a metallography laboratory imposes cleanliness and safety criteria to which your cut-off equipment must comply.
How to Mount, Polish, and Etch a Metallographic Sample
3.1. Place the sample onto the stage of the mounting press, lowering the ram via the lever on the lower left of the machine. 3.2. Pour in the appropriate amount of Bakelite. 3.3. Place the press on top, screwing it on tightly, then loosening it a quarter turn (since there is a buildup of heat and pressure during the process). then place the ram lever into the "up" position and leave it there.

The Metallographic sample is then cleaned. After cleaning, apply Kemet 1-CM Diamond Compound or Kemet 1-WP Diamond Suspension to a new cloth such as PSU-M or NHM cloth. During polishing, apply small amounts of GW2 if the cloth starts to dry out. Experiment to determine the best cloth for the sample.

Before vibratory polishing, the samples must be properly prepared using the methods described in this book including final polishing. High quality sample preparation is a basic starting point for this technique. As already explained above, vibratory polishing is dedicated to fine diamond or oxide suspensions typically between 1 and 0.02 microns.
A comparison of techniques for the metallographic
Metallographic preparation of thermal spray coated samples is often difficult because hard and soft materials, which normally require different polishing techniques, are commonly present in a single spraycoated sample. In addition, the microstructures of many spray- deposited materials make them prone to pull-out damage during cutting, grinding, and polishing operations.

oped for the mounting and embedding of metallographic samples. They are sum-marized schematically in Fig. 1.2 and can be described as two basic types of mounting: clamping with a sample holder or clamp, and embedding the speci-mens in organic or inorganic materials. Metallography / 11
What is Metallography.?
metallographic laboratories are abrasive cutoff machines. They range from small, thin-sectioning machines employing abrasive or diamond-rimmed wheels approximately 4 in. in diameter and a few mils thick to large floor-model machines employing abrasive or diamond-rimmed wheels up to 12 in. in diameter and 1/16 in. thick.
