THE PREDICTION OF ATMOSPHERIC CORROSION FROM METEOROLOGICAL AND POLLUTION PARAMETERS .2. LONG-TERM FORECASTS

Long-term atmospheric corrosion forecasts often rely on the fulfilment of equations of the form C = At(n), where C is the corrosion after t years and A represents corrosion after the first year of exposure. Appropriate values must be assigned to constants A and n. In the first part of the work an analysis was performed on the possibility of expressing A as a function of usually available environmental parameters. In this second part data compiled in a comprehensive literature survey are used to determine whether the exponent n of the above equation can also be expressed as a function of such environmental parameters.
