... is to be examined. However, because abrasive grinding and polishing steps also produce damage, where the depth of damage decreases with decreasing abrasive size, the preparation sequence must be carefully planned and performed. Otherwise, preparation induced artifacts will be interpreted as structural elements...

... with scissors. The use of 120-grit paper is not recommended as a first step because the larger abrasive size can pull out fibers and damage the specimen. A high platen speed (up to but not exceeding 1000 rpm) should be used, with moderate pressure applied to the sample. It is necessary that water is constantly...

.... If the material contacting the slurry is not corroded by the slurry liquid, as may be the case with a water slurry in plastic pipes, then the material loss will depend on the abrasion action of the slurry particles; this is where particle size is a significant factor. Nanometer- or micrometer-sized particles may...
