    Abstract

    A comprehensive research program was started in Czechoslovakia five years ago for a systematic investigation of the corrosion aggressivity of selected industrial regions. The corrosion tests were performed on 19 corrosion stations in the North-Bohemian model region. Principal technical metals were tested.

    The characteristics of climate and air pollution and also the combined index of the corrosion aggressivity were suggested and numerically expressed.

    The hyperbolic function has most closely approximated the law of the time-dependent course of the corrosion process of metals. The regression analysis was performed with the use of various forms of the climate characteristics, and the most favorable function was expressed.

    The cybernetic model of the atmospheric corrosion process was suggested.
