Název v původním jazyce

Changes in corrosion rates in atmospheres with changing corrosivity

Popis výsledku v původním jazyce

The rate of atmospheric corrosion of structural metals is significantly affected by air pollution, mainly by SO2 in industrial atmospheres. Since 90.ties of 20th century the reduction of SO2 air pollution occurred in the most part of Europe including theCzech Republic. At the test site Kopisty located at area affected by air pollution from power plants the many long-term exposure programmes had been performed since 1969. At that period the atmospheric corrosivity of this test site was C4 ? C5 accordingto ISO 9223. The results show the quickly response of structural metals´ corrosion rate on SO2 decreasing for more than 85%. The metals started to be exposed in high polluted environment slowed the corrosion rate during exposure in atmospheres with reduced SO2 in atmosphere. The trend is most evident for zinc and copper. It is very important for prediction of service life of existing structures or objects.
