| Summary: | The aim of this research is to design and fabricate a new pi I sensor that can be used to
measure hydrogen ion activity on corroding metal surface in bulk solution or under
deposit. Iridium oxide (lrOx) is used for proposed design as pH sensitive material.
IrOx is a potentiometric sensor which its open circuit potential regarding a reference
electrode is representative of pi I. The electrodcposition method of cyclic voltammetry
approach is used for coating of IrOx on stainless steel substrate. The effects of scan
rate. temperature. and number of cycles on the coating thickness of IrOx
elcctrodeposited on a stainless steel substrate v.cre investigated in a statistical system.
The central composite design. combined with response surface methodology, was
used to study condition of electrodeposition. |
