SERVI 1 showed complex spirals on the basal plane of cleaved zinc crystals after etching, and spiral terraced etch pits have been obtained on zinc crystals 2 grown from vapour using ‘Superoxol’ etch.
Etchers and etching machines remove material from the surface of a part using an acid or alkaline chemical solution. Etchers and etching machines, also known as chemical milling machines, use masking ...
THE etch-patterns on cleavage faces of calcite which have been reported 1–3 bear some interesting similarities and dissimilarities to etch-patterns obtained in this Laboratory. Watts etched calcite ...
