Triode cathodic vacuum etcher for the low-voltage polishing and etching of metallographic specimens
Description:
From international metallography society symposium on specimen preparation for metallography; Los Angeles. California, USA (23 Sep 1973). A triode cathodic vacuum etcher has been developed that has a number of advantages over conventional diode etchers. The triode etcher can be operated at specimen voltages well below 1000 V(dc) to minimize mount deterioration and the danger of arcing to the etched surface. Etching voltage and current density can be independently varied so that high current den…
