AI Article Synopsis

  • * The research involved electrochemical tests in simulated environments that mimic conditions inside and outside of a pit to analyze how benzotriazole affects pit propagation.
  • * Results indicated that both concentrations of benzotriazole showed low efficiency in preventing corrosion in acidic conditions due to challenges in forming a protective layer and issues with benzotriazole cationization.

Article Abstract

In this paper, two leaking tubes were investigated among copper tubes injected with 200 and 400 ppm benzotriazole after 8 years of usage. The electrochemical tests were conducted in simulated pit-out and pit-in environments (i.e., regions outside and inside of the pit) to determine the effect of benzotriazole on the propagation of an existing pit. The electrochemical analysis results showed that 200 and 400 ppm benzotriazole exhibit relatively lower inhibition efficiency in an acidic simulated pit-in environment because of the difficulty of forming a protective film and the benzotriazole cationization.
