Comparison of atmospheric corrosion of ACM sensors with standard flat specimens

摘要

The Fe-Ag type Atmospheric Corrosion Monitor (ACM) sensors can be used for monitoring the corrosion rate and corrosivity of various atmospheric conditions in a shorter time than the exposure test according to EN ISO 9223. The correlation between the corrosion rate of carbon steel standard flat specimens and the ACM sensors' output sensors was tested in the Czech Republic in 2013 - 2014 under outdoor and sheltered conditions at two locations: Prague, and Kopisty, representing urban, respectively industrial environments. Corrosion rates of one month exposure test were plotted as a function of the ACM sensors output to evaluate their relationships. The environmental parameters were measured continually on both atmospheric test sites too.
