Abstract
Thin-film electrical resistance (ER) sensors have been developed to monitor top-of-the-line corrosion (TLC). The objective is to address the ER measurement sensitivity and to investigate the TLC mechanism in the presence of acetic acid, monoethylene glycol (MEG), decanethiol, and diethylamine (DEA). The results showed that 1,000 ppm acetic acid increased TLC by 49%. 80 wt% MEG reduced TLC by 41%. 10 ppm decanethiol achieved TLC inhibition efficiency of 97% while 400 ppm DEA exhibited poor TLC inhibition efficiency (<15%). The ER sensors were able to record an average TLC rate of 0.03 mm/y in less than 24 h.
