SAFETY FIRST!   *As always in the laboratory setting make sure you:   -Always have lab supervision   -Are wearing safety glasses Troubleshooting - relief. Q.C. 9. Once you have finished on the finest grit of sandpaper, you should notice that the scratches are appearing smaller and smaller. This is good! Yo The etchant selectively corrodes microstructural features. Immersion time or etching time is highly dependent on the system and in most cases requires experience. Each step uses finer abrasive than the previous one, the ultimate Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface. The grinding procedure includes the use of a series of progressively finer abrasive grits. The polishing step in metallographic specimen preparation removes the last thin layer of the deformed metal for a smooth reflective surface. 8. 8.1 Check to make sure that the oxide layer is removed from the metal sample, there are no cracks in the sample, and the lines lines from the sa 2. 2.1.
