Study of Metal Etching Behavior Using an Electrochemical Polarization Technique
As part of a long range study to develop an electrochemical
measuring technique of etching rate (etching current) of metals,
we carried out potentiostatic polarization measurements of
several metals in ferric chloride etchant. The aims of this study
are:
Interpretation of etching mechanism in terms of electrochemical
process
Measurement of the absolute value of etching rate given by
an etching current.
