Specimen Preparation or Sample Machining is a first and necessary step in performing destructive testing services on metal materials. The test specimen or sample is prepared to conform to the requirements stated in the standard or specification called out for the testing that will be performed.

The next sample preparation step is grinding with a water lubricated abrasive wheel to achieve a flat, smooth and scratch-free surface. This step is required to remove the surface damage that occurred during sectioning. The grinding procedure includes the use of …grinding through the sample. When mounting is completed, begin grinding the sample on an automatic grinder with 180 grit paper. Struers Rotopol-15 operating at 400 rpm and 20 N force with water is one of many ways grinding can be performed. With this particular operating setting, 180 grit SiC paper will be spent in 30 to 45 seconds.

A mounted sample then needs grinding to create a flat and even surface. Any potential residue from the mounting process or damage from the sectioning process needs to be removed to expose the actual microstructure of the sample.Preparation may therefore include techniques such as: sectioning, mounting in conductive resin, grinding, polishing, chemical-etching, jet electro-polishing (for TEM), coating (gold or carbon). Our sample preparation service can offer some, or all, of …

A series of grinding steps follows whereby each new step makes use of even finer grinding medium, to proceed step-by-step towards the grade of polished surface desired. The sample has to be rotated through 90° after each grinding step, in order to cancel out the grooves left over from contact with the previous grinding medium.The basic steps for proper metallographic sample preparation include: documentation, sectioning and cutting, mounting, planar grinding, rough polishing, final polishing, etching, microscopic analysis and hardness testing. Documentation – Metallographic analysis is a valuable tool. By properly documenting the initial sample condition and the ...

Some sample preparation procedures then are presented for typical types of solid samples (e.g., soil and sediment, biota, food, etc.). This chapter concludes with specific guidance for preparing samples of filters (Section 12.4), wipes (Section 12.5), liquids (Section 12.6), …Bac kground. Metallographic etching is one of a number of processes that takes place during sample preparation for metallographic examination. The steps involved in preparing a sample include: • Sectioning. • Mounting. • Identification. • Grinding. • Polishing. • Cleaning.

sample for frozen section, the thickness is not as critical as paraffin processing sample, it could be 1 cm or a little bit more. 3. Fixation (optional): The sample can be fixed before or after the grossing. Again, if the sample has been fixed with formaldehyde fixatives, it should be rinsed with 1×PBS for 10 minutes, 3 times, transferred intoMetallography Part II - Microscopic Techniques- Sectioning of a sample- Wet grinding in several stages- Polishing in several stages- Etching- Observation wit...
