Abstract

In this study, Corrosion resistance of the coatings
obtained by electrochemical oxidation of pyrrole and aniline on the mild steel
has been investigated in 0.1 M hydrochloric acid medium. It was aimed to
increase the resistance of the coatings to corrosion by adding MoS₂
to the coating solutions while covering the Polypyrrole (PPy) and polyaniline
(PANI). PPy, PAN, MoS₂ doped PPy and MoS₂ doped PANI
coatings on the electrodes produced from mild steel were obtained by the Cyclic
Voltammetry method in 0,1 M H₂C₂O₄
environment. The voltamograms were carried out at a scan rate 100 V / s from
0.0 V to 1.0 V with 15 scans. The corrosion resistance of the coatings in 0.1 M
HCl medium was determined by Tafel Polarization method. Best results were
determined in MoS₂ doped PPy coatings. Later, PPy coatings, MoS₂
added PAN coatings and PANI coatings were determined respectively. The addition
of MoS₂ to the coating solution increased the corrosion resistance
in both coatings. Similar results were obtained in different environments in our
previous studies. It is understood that MoS₂ additive makes the
coating surface impermeable and prevents deformation in the coating.
