Formation, Retention, and Loss of the Metals Atmospheric Corrosion Products. 1. The Integral Weight Model of the Products Formed

Changes of the total weight of tested samples, as well as changes in the weight of the retained atmospheric corrosion products, are studied as functions of corrosion losses in different climate zones and different test duration, for carbon steel, zinc, copper, magnesium, aluminum, Ð"16 and AMЦ alloys, and brass. An experimental mathematical model for integral weight of formed corrosion products is suggested. Climate effects on the change in the weight of corrosion products retained by metals are studied during long-term exposure of plates and wire spirals recommended by the ISO 9226-92 Standard for the monitoring of atmospheric corrosivity.[PUBLICATION ABSTRACT]
