Korozyon inhibitörü olarak 1-etil-3-metilimidazolyum tetrafloroborat
(EMITFB) ve 1-bütil-1-metilpiperidinyum tetrafloroborat (BMPTFB)’ın düşük
karbon çeliğinin (St37) 0.1 M HCl ortamındaki korozyon mekanizmasına etkisi, Elektrokimyasal
Empedans Spektroskopisi (EIS) ve Potansiyodinamik Polarizasyon (TP) yöntemleri
kullanılarak araştırılmış ve sonuçlar kıyaslanmıştır. Elektrokimyasal
ölçümlerden sonra metal yüzeyindeki morfolojik değişiklikler Taramalı Elektron
Mikroskobu (SEM) ve Enerji Kırınımı X-Işını Spektroskopisi (EDS) yardımıyla
analiz edilmiştir. Elde edilen bulgular, çalışılan her iki bor katyonlu iyonik
sıvının ihibitör olarak kullanılabileceğini göstermektedir. St37 çeliğinin 0.1
M HCl ortamındaki BMPTFB ve EMITFB kullanılmasına bağlı olarak hesaplanan
inhibitör etkinliği (%IE) değerleri sırasıyla
%87 ve %73’tür. St37 çeliğinin 0.1 M HCl ortamında korozyonuna BMPTFB’nin EMITFB’ye
kıyasla yaklaşık %15 daha iyi koruduğu görülmüştür. 

Anahtar Kelimeler

USING OF IONIC LIQUIDS CONTAINING BORON CATION AS CORROSION INHIBITOR IN 0.1 M HCl ENVIRONMENT

Öz

The corrosion inhibition effect of
1-ethyl-3-methylimidazolium tetrafluoroborate (EMITFB) and
1-butyl-1-methylpiperidinium tetrafluoroborate (BMPTFB) as corrosion inhibitors
was investigated on low carbon steel in 0.1 M HCl environment using
Electrochemical Impedance Spectroscopy (EIS) and Tafel Polarization (TP)
methods. The results from the two electrochemical techniques were compared.
Morphological changes on the metal surface after electrochemical measurements
were analyzed with the aid of Scanning Electron Microscopy (SEM) and Energy
Diffraction X-Ray Spectroscopy (EDS). The findings show that the studied boron
cationic ionic liquids can be used as inhibitor. The optimum inhibition
efficacy (% IE) of 87% and 73% was achieved for BMPTFB and EMITFB respectively.
It has been found that BMPTFB inhibits the steel corrosion by approximately 15%
better than EMITFB in the considered acid environment.
