Investigation of the effects of atmospheric acidity upon economically significant materials. Final report
Technical Report

OSTI ID:5437883
Materials of economic significance were exposed at three sites in Southern California (Burbank, Long Beach and Upland) and at a background site in Central California (Salinas) during the time between March 1986 and August 1990. Corrosion damage was determined by weight loss for galvanized steel, nickel, aluminum and two paints. For nylon fabric, the loss of breaking strength was used as a measure of corrosion damage. A multivariate regression analysis of the experimental corrosion and aerometric data showed that the observed corrosion damage could be explained satisfactorily for galvanized steel, nickel, and aluminum using variables related to O3 concentrations and relative humidity. However, because the relationship of O3 to the underlying, direct agents of corrosion is site specific, the results are valid only for the monitoring sites included in the study.
