Chemical etching may be necessary to reveal micrstructure, or to prepare a specimen surface for testing and characterization. Electropolishing avoids issues with surface deformation present in mechanical polishing and/or interaction with water and other polishing media. All chemical etching must be performed in a chemical fume hood according to the safety requirements of the Chemical Hygiene Plan (CHP).
Some etchants are have highly restricted use due to safety concerns. Discuss use of these materials with the MSE Safety Committe prior to using in the lab.
