"Lectropol-5: A Microprocessor controlled electrolytic polishing and etchin
g unit for the software controlled, automatic preparation of metallographic
al specimens. Includes scanning functions for the easy determination of dat
a, built in safety functions and a data bank containing methods of preparat
ion for numerous materials which will ensure both the shortest polishing ti
mes and highest reproducibility". These are the claims made in the brochure
on this new piece of equipment, and we were of course interested. We thus
tested the possible uses of the new unit on specimens of twenty different m
aterials.
