Grinding & Polishing Either 240 [P280] or 320 [P400] grit SiC waterproof paper may also be used for the planar grinding step. An UltraPol cloth produces better surface finishes than an UltraPad cloth, but the UltraPad cloth has a longer useful life. A ChemoMet cloth is recommended when edge retention is critical.
Grinding and Polishing With grinding, saw marks and levels are removed and the sample surface is cleaned. The artifacts of grinding are eliminated with very little material removal through polishing. Fixed abrasives composed of abrasive particles bonded to the paper or plates are used in the grinding process for fast material removal.
After grinding the specimen, polishing is performed. Typically, a specimen is polished with a slurry of alumina, silica, or diamond on a napless cloth to produce a scratch-free mirror finish, free from smear, drag, or pull-outs and with minimal deformation remaining from the preparation process.
To remove deformations and scratches from Fine Grinding and obtain a surface that is highly reflective, samples must be polished before they can be examined under the microscope. To achieve efficient material removal and to cut consistently through all materials and phases, the …
grinding and polishing steps. As a result of sectioning and grinding, the material may get cold worked to a considerable depth with a resultant transition zone of deformed material between the surface and the undistorted metal. Course grinding can be accomplished either wet or dry using 80 to 180 grit electrically
